Using strain gages properly
with trainings from ZSE

Electrical strain gages are used for high-precision stress analysis for a wide variety of components and designs and in transducer construction. A large number of strain gage types are available for this purpose. It is the user's responsibility to install them on the components to be examined, to establish the connection to suitable measuring amplifiers, to carry out and evaluate the measurements, and finally to draw conclusions about the stress and operational safety.

High-quality measurements therefore require the use of suitable strain gages as well as trained users who are able to perform proper installation, instrumentation and strain evaluation.

ZSE Electronic Mess-Systeme & Sensortechnik GmbH supports potential strain gage users in room and high temperature applications in selecting strain gages, accessories and amplifiers. Furthermore, ZSE offers certified training courses according to VDI/VDE guideline 2636 in the entire strain gage application area.

To the course offers

Strain gage trainings from ZSE - also possible online

The strain gage training courses offered by ZSE provide the user with knowledge and skills about strain gage installation, measurement, analysis and evaluation of the results. In addition, a special course on the basics and application of high temperature strain gages is offered. These courses can now also be booked as online training. For this purpose, ZSE has set up an online training laboratory in which high-quality cameras and microphones allow the transmission of theoretical lectures and practical exercises in high quality.

Profound specialist knowledge

The training courses are held by Dr.-Ing. habil. Martin Stockmann. Mr. Stockmann has been working intensively in the field of research and application of electrical strain gages for over 30 years. This is expressed, among other things, in a large number of international publications and the former long-standing leadership of the technical committee "Electrical Strain Gages" at the VDI.

The trainings take place at the ZSE head office in Bietigheim-Bissingen or in special cases also on-site at the users office or workshop.

The course offer

The training is held according to the guideline VDI/VDE 2636 by courses 1-3. In addition, a special course 4 can be booked, which deals with questions of strain gage technology in the high temperature range. Individual combinations of the courses are also possible by arrangement.
