Note: Each 5-pole plug requires 1 plug housing, 5 contact pins, and 5 individual gaskets.For automotive applications, original AMP crimping tools must be used.

ApplicationIn order to comply with the vehicleemission limits demanded by law, it isnecessary to maintain a given air/fuel ratioexactly.This requires sensors which preciselyregister the actual air-mass flow and outputa corresponding electrical signal to theopen and closed-loop control electronics.

DesignThe micromechanical sensor element islocated in the plug-in sensors flowpassage. This plug-in sensor is suitable forincorporating in the air filter or, using ameasurement venturi, in the air-intakepassages. There are different sizes of mea-surement venturi available depending uponthe air throughflow. The micromechanicalmeasuring system uses a hybrid circuit,and by evaluating the measuring data isable to detect when return flow takes placeduring air-flow pulsation.

Operating principleThe heated sensor element in the air-massmeter dissipates heat to the incoming air.The higher the air flow, the more heat isdissipated. The resulting temperature differ-ential is a measure for the air mass flowingpast the sensor.An electronic hybrid circuit evaluates thismeasuring data so that the air-flow quantitycan be measured precisely, and itsdirection of flow.Only part of the air-mass flow is registeredby the sensor element. The total air massflowing through the measuring tube isdetermined by means of calibration, knownas the characteristic-curve definition.

Ratiometric signal evaluation(referred to supply voltage). Self-monitoring of offset andsensitivity. Protection against polarityreversal, overvoltage, andshort circuit of output to supplyvoltage or ground. High level of compatibilitywith media since this onlycomes into contact with

stainless steel. Resistant to brake fluids,mineral oils, water, and air.

ApplicationPressure sensors of this type are usedto measure the pressures in automotivebraking systems, or in the fuel-distributorrail of a gasoline direct-injection engine,or in a diesel engine with Common Railinjection.

Design and functionPressure measurement results from thebending of a steel diaphragm on which arelocated polysilicon strain-gauge elements.These are connected in the form of aWheatstone bridge. This permits highsignal utilisation and good temperaturecompensation.The measurement signal is amplified in anevaluation IC and corrected with respect tooffset and sensitivity. At this point, tempera-ture compensation again takes place sothat the calibrated unit comprisingmeasuring cell and ASIC only has a verylow temperature-dependence level.Part of the evaluation IC is applied for adiagnostic function which can detect the

following potential defects: Fracture of a bonding wire to themeasuring cell.

Fracture anywhere on any of the signallines.

Fracture of the bridge supply andground.

Only for 0 265 005 303This sensor differs from conventionalsensors due to the following diagnosticfunctions: Offset errors Amplification errorscan be detected by comparing two signalpaths in the sensor.

Storage conditionsTemperature range 30...+60 CRelative air humidity 0...80 %Maximum storage period 5 yearsThrough compliance with the abovestorage conditions, it is ensured that thesensor functions remain unchanged.If the maximum storage conditions areexceeded, the sensors should no longer beused.

ApplicationsVibration sensors of this type are suitable forthe detection of structure-borne acousticoscillations as can occur for example in caseof irregular combustion in engines and onmachines. Thanks to their ruggedness,these vibration sensors can be used evenunder the most severe operating conditions.

Areas of application

Knock control for internal-combustionengines Protection of machine tools Detection of cavitation Monitoring of bearings Theft-deterrent systems

Design and functionOn account of its inertia, a mass exertscompressive forces on a ring-shapedpiezo-ceramic element in time with theoscillation which generates the excitation.Within the ceramic element, these forcesresult in charge transfer within the ceramicand a voltage is generated between thetop and bottom of the ceramic element.This voltage is picked-off using contactdiscs in many cases it is filtered andintegrated and made available as ameasur-ing signal. In order to route thevibration directly into the sensor, vibrationsensors are securely bolted to the objecton which measurements take place.

Measurement sensitivityEvery vibration sensor has its own individualresponse characteristic which is closelylinked to its measurement sensitivity. Themeasurement sensitivity is defined as theoutput voltage per unit of acceleration dueto gravity (see characteristic curve). The

production-related sensitivity scatter isacceptable for applications where theprimary task is to record that vibration isoccurring, and not so much to measure itsseverity.The low voltages generated by the sensorcan be evaluated using a high-impedanceAC amplifier.

MAP SENSORS


Manifold Absolute Pressure Sensors, or MAP Sensors as they are morecommonly known, are used to measure inlet manifold pressure to give anindication of engine load.These sensors are generally used in Speed/Density or Manifold PressureControlled engine management systems that do not use an Air Flow/MassSensor.The MAP sensor measures Absolute pressure not Gauge pressure, sonormal atmospheric pressure is a value of 1 bar. If used on a turbochargedvehicle where manifold pressure can be higher than atmospheric pressure,a sensor that measures up to 2 bar or more may be required, dependent onboost pressure developed.The diagram below visually represents range requirements of the sensor tosuit certain applications. For example a normally aspirated engine would notrequire anything higher than 1 bar.A turbocharged engine with 0.5 bar boost would require a 2 bar sensor.Evolution of the MAP Sensor by Bosch has seen the creation of an inte-grated temperature and MAP Sensor referred to as aT-MAP sensor. These sensors allow the engine management system toaccurately detect both manifold pressure and inlet air temperature with-in one sensor in order to make an accurate assessment of the weight ormass of air being inducted by the engine.

Piezoresistive absolute-pressure sensorsin thick-film technologyMeasurement of pressures in gases up to 250 kPa

Design and functionThe heart of this sensor is the sensorbubble (pressure-measuring element)produced using 100% thick-filmtechniques.It is hermetically sealed on a ceramicsubstrate and contains a given volume ofair at a reference pressure of approx. 20kPa. Piezo-resistive thick-film strain gaugesare printed onto the bubble and protected

with glass against aggressive media. Thestrain gauges are characterized by highmeasurement sensitivity (gauge factorapprox. 12), as well as by linear andhysteresis-free behavior. When pressure isapplied, they convert mechanical strain intoan electric signal. A full-wave bridge circuitprovides a measurement signal which isproportional to the applied pressure, andthis is amplified by a hybrid circuit on thesame substrate. It is therefore impossiblefor interference to have any effect throughthe leads to the ECU. DC amplification andindividual temperature compensation inthe 40C...+125C range, produce ananalog, ratiometric (i.e. proportional to thesupply voltage UV) output voltage UA. Thepressure sensors are resistant to gaugepressures up to 600 kPa.Outside the temperature range10C...85C the permissible toleranceincreases by the tolerance multiplier. Toprotect the sensors, the stipulatedmaximum values for supply voltage,operating-temperature, and maximumpressure are not to be exceeded.

Absolute-pressure sensorsin micromechanical hybrid designMeasurement of pressures in gases up to 400 kPa

Applications

This sensor is used to measure theabsolute intake-manifold pressure. On theversion with integral temperature sensor,the temperature of the drawn-in air flow isalso measured.

Design and functionThe piezoresistive pressure-sensor elementand suitable electronic circuitry for signal-amplification and temperaturecompensation are mounted on a siliconchip. The measured pressure is appliedfrom above to the diaphragms activesurface. A reference vacuum is enclosedbetween the rear side and the glass base.Thanks to a special coating, both pressuresensor and temperature sensor areinsensitive to the gases and liquids whichare present in the intake manifold.

Installation informationThe sensor is designed for mounting on ahorizontal surface of the vehicles intakemanifold. The pressure fitting together withthe temperature sensor extend into themanifold and are sealed-off to atmosphereby O-rings. By correct mounting in thevehicle (pressure-monitoring point on thetop at the intake manifold, pressure fittingpointing downwards etc.) it is to be en-sured that condensate does not collect in

the pressure cell.

High accuracy.EMC protection better than100V m1. Temperature-compensated.Version with additionalintegral temperature sensor.

Piezoresistive absolute-pressure sensorwith moulded cableMeasurement of pressures in gases up to 400 kPa

ApplicationsThis type of absolute-pressure sensor ishighly suitable for measuring the boostpressure in the intake manifold of turbo-charged diesel engines. They are neededin such engine assemblies for boost-pressure control and smoke limitation.

Design and functionThe sensors are provided with a pressure-

connection fitting with O-ring so that theycan be fitted directly at the measurementpoint without the complication and costs ofinstalling special hoses. They are extremelyrobust and insensitive to aggressive mediasuch as oils, fuels, brake fluids, saline fog,and industrial climate.In the measuring process, pressure isapplied to a silicon diaphragm to which areattached piezoresistive resistors. Usingtheir integrated electronic circuitry, thesensors provide an output signal thevoltage of which is proportional to theapplied pressure.

Installation information

The metal bushings at the fastening holesare designed for tightening torques ofmaximum 10 Nm.When installed, the pressure fitting mustpoint downwards. The pressure fittingsangle referred to the vertical must notexceed 60.

TolerancesIn the basic temperature range, themaximum pressure-measuring error p(referred to the excursion: 400 kPa50 kPa= 350 kPa) is as follows:Pressure range 70...360 kPa

As-new state 1.0 %

After endurance test 1.2 %Pressure range < 70 and > 360 kPa (linearincrease)

ApplicationsThese monolithic integrated siliconpressure sensors are high-precisionmeasuring elements for measuring theabsolute pressure. They are particularlysuitable for oper-ations in hostileenvironments, for instance for measuringthe absolute manifold pressure in internal-combustion engines.

Design and functionThe sensor contains a silicon chip withetched pressure diaphragm. When achange in pressure takes place, thediaphragm is stretched and the resultingchange in resistance is registered by anevaluation circuit. This evaluation circuit isintegrated on the silicon chip together withthe electronic calibration elements. Duringproduction of the silicon chip, a siliconwafer on which there are a number ofsensor elements, is bonded to a glassplate. After sawing the plate into chips, theindividual chips are soldered onto a metalbase complete with pressure connectionfitting. When pressure is applied, this isdirected through the fitting and the base tothe rear side of the pressure diaphragm.There is a reference vacuum trappedunderneath the cap welded to the base.This permits the absolute pressure to bemeasured as well as protecting the frontside of the pressure diaphragm. Theprogramming logic integrated on the chipperforms a calibration whereby thecalibration parameters are permanentlystored by means of thyristors (Zener-Zapping) and etched conductive paths.The calibrated and tested sensors aremounted in a special housing forattachment to the intake manifold.

Signal evaluationThe pressure sensor delivers an analogoutput signal which is ratiometric referredto the supply voltage. In the input stage ofthe downstream electronics, werecommend the use of an RC low-passfilter with, for instance, t= 2 ms, in order tosuppress any disturbance harmonics whichmay occur. In the version with integratedtemperature sensor, the sensor is in the

BMOTORSPORT COMPONENTS


Oxygen Sensors are used to detect the amount of excess oxygen in the

exhaust gas after combustion to indicate the relative richness or lean-ness of mixture composition.

The oxygen sensor contains two porous platinum electrodes with a

ceramic electrolyte between them. It compares exhaust gas oxygenlevels to atmospheric oxygen and produces a voltage in relation to this.

The voltage produced by the oxygen sensor will be typically as small as100 mV [lean] up to a maximum of 900 mV [rich]. An active oxygen sen-sor would cycle between these two points as the engine management

system drives the mixture rich and lean to achieve an average sensorvoltage of ~465mV. This would represent the mixture ratio of 14.7:1.

This type of operation is normal for a narrow band style of sensor;these are used for the majority of standard vehicle applications.Bosch also produces lean sensors [type code LSM11] for testingapplications, these provided a broader operational range by extending thelean scale, a detailed curve can be seen below. These sensors are notrecommended for standard vehicle use.

The introduction of Planar manufacturing technology has allowedBosch to produce a wide band oxygen sensor that has an extended

mixture operating range [type code LSU4]. These sensors operate on acompletely different principle to the standard thimble type sensormanufactured by Bosch. The operation of this type of sensor requires

various software controls to manage oxygen cell current requirements,signal interpretation and heater management. Bosch produces these sen-sors for use with our engine management systems that are developed in

conjunction with individual vehicle manufacturers.It should be noted that these sensors require a complex heater

management system in order to maintain sensor accuracy acrossvarious operating conditions. Sensors not operated in conjunction withan appropriate heater management strategy may be damaged due to

thermal stress. Consultation with the engine management system provider

should take place prior to use of these sensors to ensure they are sup-ported.

Principle of the galvanicoxygen concentration cell withsolid electrolyte permits mea-surement of oxygenconcentration, for instance inexhaust gases. Sensors with output signalwhich is both stable andinsensitive to interference, aswellas being suitable for extreme

operating conditions.

Installation instructionsThe Lambda sensor should be installed ata point which permits the measurement ofa representative exhaust-gas mixture, andwhich does not exceed the maximumpermissible temperature. The sensor isscrewed into a mating thread and tightenedwith 5060 N m.

Install at a point where the gas is as hot

as possible. Observe the maximum permissibletemperatures. As far as possible install the sensorvertically, whereby the electricalconnections should point upwards. The sensor is not to be fitted near to theexhaust outlet so that the influence of theoutside air can be ruled out. The exhaust-gas passage opposite the sensor must befree of leaks in order to avoid the effects ofleak-air. Protect the sensor against condensationwater. The sensor body must be ventilated fromthe outside in order to avoid overheating. The sensor is not to be painted, nor iswax to be applied or any other forms oftreatment. Only the recommended greaseis to be used for lubricating the threads. The sensor receives the reference airthrough the connection cable. This meansthat the connector must be clean and dry.Contact spray, and anti-corrosion agentsetc. are forbidden. The connection cable must not besoldered. It must only be crimped,clamped, or secured by screws.

Design and functionThe ceramic part of the Lambda sensor(solid electrolyte) is in the form of a tubeclosed at one end. The inside and outsidesurfaces of the sensor ceramic have amicroporous platinum layer (electrode)which, on the one hand, has a decisiveinfluence on the sensor characteristic, andon the other, is used for contactingpurposes. The platinum layer on that part ofthe sensor ceramic which is in contact withthe exhaust gas is covered with a firmlybond-ed, highly porous protective ceramiclayer which prevents the residues in theexhaust gas from eroding the catalyticplatinum layer. The sensor thus featuresgood long-term stability.The sensor protrudes into the flow ofexhaust gas and is designed such that theexhaust gas flows around one electrode,whilst the other electrode is in contact with

the outside air (atmosphere).Measurements are taken of the residualoxygen content in the exhaust gas.The catalytic effect of the electrode surfaceat the sensors exhaust-gas end producesa step-type sensor-voltage profile in thearea around = 1. 1)

The active sensor ceramic (ZrO2) is heatedfrom inside by means of a ceramic Wolframheater so that the temperature of thesensor ceramic remains above the 350 Cfunction limit irrespective of the exhaust-gas temperature. The ceramic heaterfeatures a PTC characteristic, whichresults in rapid warm-up and restricts thepower requirements when the exhaust gasis hot. The heater-element connections arecompletely decoupled from the sensorsignal voltage (R 30 M). Additionaldesign measures serve to stabilize the leancharacteristic-curve profile of the TypeLSM11 Lambda sensor at > 1.0...1.5 (forspecial applications up to = 2.0): Use of powerful heater (16 W) Special design of the protective tube Modified electrode/protective-layersystem.

1) The excess-air factor () is the ratio be-tween the actual and the ideal air/fuel ratio.

The special design permits: Reliable control even with low exhaust-gas temperatues (e.g. with engine at idle), Flexible installation unaffected by externalheating, Function parameters practicallyindependent of exhaust-gas temperature, Low exhaust-gas values due to thesensors rapid dynamic response, Little danger of contamination and thuslong service life, Waterproof sensor housing.

DesignHall sensors comprise a semiconductorwafer with integrated driver circuits (e.g.Schmitt-Trigger) for signal conditioning, atransistor functioning as the output driver,and a permanent magnet. These are allhermetically sealed inside a plastic plug-type housing.

Application

Hall-effect rotational-speed sensors areused for the non-contacting (proximity), andtherefore wear-free, measurement ofrotational speeds, angles, and travelleddistances. Compared to inductive-typesensors, they have an advantage in theiroutput signal being independent of therotational speed or relative speed of therotating trigger-wheel vane. The position ofthe tooth is the decisive factor for the outputsignal.Adaptation to almost every conceivableapplication requirement is possible byappropriate tooth design. In automotiveengineering, Hall-effect sensors are usedfor information on the momentary wheelspeed and wheel position as needed forbraking and drive systems (ABS/TCS), formeasuring the steering-wheel angle asrequired for the vehicle dynamics controlsystem (Electronic Stability Program, ESP),and for cylinder identification.

Operating principleMeasurement is based upon the Hall effectwhich states that when a current is passedthrough a semiconductor wafer the so-called Hall voltage is generated at rightangles to the direction of current. Themagnitude of this voltage is proportional tothe magnetic field through the

semiconductor. Protective circuits, signalconditioning circuits, and output drivers areassembled directly on this semiconductor.If a magnetically conductive tooth (e.g. ofsoft iron) is moved in front of the sensor,the magnetic field is influenced arbitrarilyas a function of the trigger-wheel vaneshape. In other words, the output signalsare practically freely selectable.
