THE IMI sensors division of PCB Piezotronics has introduced Model 685A01, 24V dc powered, electronic vibration switch with explosion-proof housing.
The vibration switch, available from Davidson Measurement , provides early warning of machine deterioration and will shut the machine down when the trip level is exceeded, preventing catastrophic damage and expensive repairs.
Features include Form C (SPDT) relay, adjustable trip point, local and remote reset, and continuous or latch relay operation.
Operating range is 0 to 10g from 10 to 1000Hz. This is suitable for predictive maintenance on pumps, fans, blowers, compressors, gearboxes, as well as any other rotating equipment.
