In addition to the standard functions, signal conditioners and measuring transducers for explosion protection guarantee electrical explosion protection for all substance groups and areas in accordance with the relevant standards. Due to the consistent product development and evaluation in accordance with SIL IEC 61508 and PL DIN EN ISO 13849, our signal conditioners and measuring transducers minimize hazards to an acceptable residual risk and ensure the protection of people, machines, and the environment.
