Description
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.
