Our Product Range

Imagine a world where everything is mobile. Any device you can imagine runs without a cable. That is the world we believe in. And that is why we work day after day to reliably and safely provide this energy - anywhere, anytime.

Mobile Energy Supply

All from a single source: for over 30 years we have been developing and manufacturing transmitters, pressure controllers and customised measuring systems for building automation, clean room technology and industrial applications.

Measuring systems 

Imagine a reliable transformer with a fuse that will not trigger despite frequent switching on and off. To make this scenario a reality, we have developed a transformer switching relay completely cutting out - not just reducing - the switch-on surge in your transformer.
