History and Structure More than 20 companies with more than 150 employees evolved from the company

"Gruppe Ingenieurbau München", founded in 1976 in the city of München in Germany. DOLI

Elektronik GmbH is one of those companies, the founders of which have their roots in the

weighing technology, processor system development and general measuring and control

engineering. Nowadays, DOLI has six partners, two of them managing. In 2008, DOLI obtained

a turnover of approximately 4.5 Mio. EURO in three locations and with 35 employees. Managing Partners: Ernst Ams, Michael Grupp Further Partners: Klaus Böck, Rolf Grupp, Hermann Schabel, Harald Schmid Employees 35

Turnover 2008 approx. 4.5 Mio. EURO

Registered Capital 150,000 EURO

HRB München 52456

Know - How

Detection of physical outputs, such as: load, position, strain, time, angle, temperature, acceleration.

Amplifier and AD-conversion: standard ±180.000 digits in real-time.

Incremental detection systems: Sinusoidal signal desampling, high counting frequencies.

Digital control of electrical and hydraulic drives, especially for static and dynamic testing.

Safety technologies, such as: Limit switch, limit values, transmission protocol, emergency stop, shielding.

Real-time systems: multitasking, synchronization.

Using contemporary technologies (SMD, PLD), powerful electronic components are constructed in a compact design.

Development and production of exchangeable componentry (exchange without post-adjusting).

Electronics for Material Testers: New electronics for Screw Testers. Existing material testers with electrical drive will be equipped with a new controller. If necessary, the motor will be changed, too. With this RetroFit, you will have a state of the art testing system with closed loop control. Additional appliances (e.g. Extensometer) will be adapted or DOLI delivers new ones. DOLI retrofits all kinds of testing systems - independent from the producer.

Modernisation of Hydraulic Testers.

Hydraulic testing systems will be modernised according to the task and existing equipment. Even manually controlled instruments with plunger of an older style will be equipped with new hydraulics and a servo valve. Hence, an automatic test run will be guaranteed even with these kinds of instruments. DOLI has been retrofitting testing instruments since 1979. And from 1986 on, DOLI retrofits with closed loop control.

Modernisation of Dynamic Testing Systems.

With the EDC580, DOLI retrofits dynamic testing systems, also. With the RetroFit, even testing with frequencies of up to 500Hz can be realized! DMA- and energy calculations will be possible as well as an analysis of the elastic stiffness. Whether static or dynamic – it does not matter to us: DOLI offers the complete solution for your tester! It contains control electronics and software, the exchange of motors or hydraulic power packs, as well as the repair of cylinders or the adaptation or exchange of transducers or additional accessories.


Linear Motors. For the „low-load“-range, DOLI offers Linear Motors as cost effective alternatives to the more expensive hydraulic or compressed-air systems. These linear motors are available as AC- or DC-linear motors for different applications and they can be used together with the EDC and the Test&Motion Software.

Test&Motion Software for Material Testing Applications.

Evaluation software for almost all kinds of applications

Data detection, with PC

Test control, with PC

Test analysis, with PC

Data-logging, with PC

Control of dynamic and static instruments

Test&Motion DynPack – the Software for Dynamic Applications

Display and procession of up to 10 channels simultaneously

Data transfer with 5kHz

Control of multiaxial systems

Oscilloscope function for dynamic applications

Display of covering curve

Limit assignment in a absolute and relative manner

Function generator for ramps, triangle and sinusoidal functions

Sweep between frequencies and amplitudes

Superimposition of different curve forms


Measuring Technology PC-Incremental Boards

PC-incremental boards for the direct acquisition of four rectangle or sinusoidal incremental transducer signals. The PCINC4-board is based on a state-of-the-art board with eight additional digital I/Os. She replaces the PCINC3-board. These boards have been designed especially for OEM customers in the field of measuring instruments. PC104-board for the direct connection of two incremental transducers


The DOLI Compression Flexometer Family: Standard (“Goodrich”) or Ultimate, manual or fully automated!

The Standard DOLI Compression Flexometer, known as “Goodrich Flexometer” also, still has the classic eccentric drive. But the Ultimate Flexometer is driven by an energy saving and environment friendly linear motor! Both instruments are available as manual or fully automated version. The fully automated version, including a handling system for the rubber samples, supplies results without staff influence. Unpopular handling and adjusting is eliminated. Temperature measurements are done with the puncture needle immediately. Therefore, measurement errors by temperature loss are almost eliminated. With the newly developed WindowsTM Software DOLIFlex and its functions “Multichart” and “Calibration”, the DOLI Flexometer is completed to a versatile and easy-to-use testing system!


München : Headquarters, Management and R & D

The DOLI centre for hard- and soft-ware development can be found in München. This is the point, where all products get created and prepared up to serial production. Special tasks, such as testing systems or special electronics for customers are generated exclusively at this de-partment. 16 employees, mostly engineers for hard- and software development create solutions for the most effective combinations of new and existing technologies and the best price.

Using powerful software tools makes soft- and hardware developments much more efficient.

Programming digital hardware in PLDs increases the functionality and efficiency, at the same time this means a safe of time and costs.

Separate Boot- and BIOS- programs enable the application of a standard interface from the software to the hardware as well as upward compatibility.

The DOLI Multitasking-Kernel and the Interrupt-Processing are the best conditions for real-time application.

Software Updates for the Micro-Controller-Hardware is done by a simple download into a Flash-EPROM. This is a big advantage in case of service needs.

Continuous testing of new technologies and componentry in purpose of finding possible improvements for DOLI products and customer products


Ehingen/Donau : Production In our department in Ehingen, we use a computer controlled production planning system to control the material management and the production.

The raw material stock contains more than 5,000 different electronic and mechanic components. The components will get distributed and placed for the different production orders. Following TQM-directions, we calibrate and check the processed componentries at modern measuring desks.

Single componentries are produced in advance, whereas complete appliances are produced in an order-related manner. This guarantees a fast reaction time on orders and a variable and flexible production process. The finished appliances and compo-nentries will be subject to an automatical final test.


Stadecken-Elsheim (Frankfurt Area) : Sales/Service With its location in the Rhein-Main-Area, the sales department in Stadecken-Elsheim close to Frankfurt is much more centralised than the headquarters in München. This enables DOLI to serve its customers in a very fast and cost effective manner. Furthermore, the vicinity to the airport in Frankfurt offers the possibility to serve even international customers in a fast and flexible way. The main tasks are the following:

Introduction of new products by brochures, commercial etc.

Marketing for existing and new products

Complete design and project work for exhibitions

Customer offers including offer creation and all following tasks

Customer service with pre- and after sales service

Service point for DOLI Systems


DOLI OEM Products are compatible amongst themselves! If you have developed (or adapted your existing) software for a DOLI electronics system once,

you can connect to a new DOLI product very fast.

EDC5/25, EDC100, EDC60, EDC120, EDC220, EDC222, EDC580, EDC220V, EDC222V, EDC580V

and the following products. You choose the desired electronics with the exact resolution

and the exact price for the exact application → for your best profit.

Worldwide, more than 25,000 digital controlled testing instruments are running with DOLI controllers !
