We have been designing and producing electronic devices in Schwaebisch Hall for more than 40 years. Our first design was a Thermistor-Relay. Since this time, our range of products has enlarged continually. For instance we have devices that communicate via Internet. Our range of products has five focuses:

There are Temperature-Relays with Sensors. on the one hand. In this group of products, we are still producing our first "baby", the Thermistor-Relay. These devices monitor temperatures in motors, transformers or plants with sensors Pt 100 (RTD), PTC-Thermistors of Thermocouples.

The second focus are devices for monitoring grids. They monitor phase, voltage, current and frequency in electric plants. Space-saving Electronic Current-Transformers capture the current-flow in a conductor.

Our Digital Panelmeters for measuring various signals are the third group. They are used where measured values shall be displayed. Alarm-outputs and integrated measuring-transducers expand the scope of applications.

The forth group are Switching Relays and Controls. Especially to be mentioned are controls for suction plants, speed monitors or level-relays for conductive liquids.

Measuring Transducers for temperature and electric values like AC and DC voltage or current or resistance complete our range of products.

Besides that we deal with special assignments and offer our customers the development and production of special solutions, customized for their application.
