The measurements must be reliable at temperatures from -40 to 105 °C and comply with strict standards such as the ISO 26262. Other challenges include accurate voltage measurement and the detection of insulation faults.

Our sensors work reliably in a wide temperature range and are developed in accordance with the functional safety standards ASIL C for current measurements and ASIL B for voltage measurements.

This increases the safety of the overall system in which the sensors are installed. The ability to measure insulation also helps to detect and rectify faults in the system at an early stage.

High
system security

Thanks to their precise design, our solutions contribute to a high level of system reliability.
