Sensors

HKS Sensoren Produktuebersicht

HKS offers measurement value sensors for all relevant welding processes. These calibrated sensors enable the use of welding technology in every welding system irrespective of the manufacturer.

Sensors are characterised by their high robustness. They can also be used under the most extreme conditions (high-voltage ignition for TIG welding)

due to intelligent protection circuits and a logical galvanic separation.

Depending on the process variables, you can select:

Current / voltage

Current and voltage are measured based on the principle of a compensated hall sensor. They can be used from standard measurements to comparison measurements for calibrating the display devices of welding systems used (device calibration)
