PCH Engineering A/S products

The PCH 1220 Electronic Vibration Switch provides basic, reliable protection of rotating machinery at a low cost. An electronic vibration switch has no moving parts that can become stuck. The electronic signal is also more accurate and has a higher degree of repeatability than a mechanical switch. In choosing an electronic vibration switch such as the PCH 1220, you are opting for the more reliable – and hence safer – solution.

The PCH 1270 and PCH 1272 vibration transmitters with internal vibration sensors are ideal as part of the safety chain for dangerous machinery when high accuracy and fast response times are important.

PCH 1290 is a simple, cost-effective and safe machine monitoring solution offering full redundancy. The fully redundant vibration monitor comes with two individual sensors in one casing. This means that you only need to mount one device to get the data input of two vibration sensors.  PCH 1290 is suitable for enhanced SIL 2 protection in compliance with EN 13849, as each of the two individual processors and alarm relays work simultaneously in one vibration guard.
