Through redundant pressure measurement, signal processing and two independent output signals, a controlside plausibility monitoring is ensured. This increases the process reliability, saves space and significantly reduces the installation costs over the use of two independent pressure transmitters. Robust design for rough conditions The model MHS has been designed for the extreme and harsh conditions in mobile hydraulic equipment. A hermetically welded WIKA thin-film measuring cell, the stainless steel case and the metal M12 connector make this pressure transmitter particularly t n ough. Through this robust design, the model MHS achieves an IP 69K ingress protection.
