Recognised Component Mark  

The Recognised Component Mark from UL (left) may be used for components parts that are part of a larger product or system. Many of our custom power supplies have this certification.


Automation Valley

Innovation by cooperation with partners of control and automation engineering, possible by membership in Automation Valley.


We are member of AS-INTERFACE.


We belong to PROFIBUS User Organization


LonWorks-technology refers to a universal automation network and is a worldwide standard for the automation of buildings and industrial plants.
Our energy management systems and measuring transducers are equipped with this interface.

M-Bus / L-Bus  

For the development of M-Bus applications we consider the requirements of the M-Bus User Group at Paderborn University.
L-Bus devices work with the same protocols as M-Bus devices, but with very low signal levels.


HART - Highway Addressable Remote Transducer - is an open communication protocol for industrial measuring instruments - many of our transducers can work with this protocol.


The Controller Area Network is used in the automotive industry, the factory automation and for machine control. We support this with our temperature controllers.


MODBUS Protocol is a messaging structure developed by Modicon in 1979, used to establish master-slave/client-server communication between intelligent devices.
It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment. Our energy management systems and transducers are also available with this protocol.


We incorporate our know-how into national and international safety standards by means of active participation in the development of normative documents



Many of our instruments have been distinguished with several safety relevant awards

  • CE, GS, UL
  • EX - ATEX-Certificate
  • GL (German Lloyd)
  • VDE (D), SEV (CH)
  • CSA (Canada)
  • KemaKeur (NL)
