Product Details

Overview
The transmitter adopts a two-wire system and provides a 4-20mA current signal, which is proportional to the vibration speed of the bearing bush or bearing seat of the rotating machinery. It automatically collects the vibration signal on the machine, and uses the converted analog signal for PLC, DCS and DEH systems, etc.

Fields of application
For rotating and reciprocating machines such as: fans, centrifuges, pumps, electric motors, gear units, industrial fans, heat exchangers/cooling towers, air-cooled island fans , generators, piston compressors, centrifugal compressors, Crusher, compressor, pump, coal mill, etc.
