IMI Sensors ’ Vibration Alarm Modules Provide Alarm and Shutdown Protection for Machinery

August 7, 2007—

The Series 684 indicator alarm module from IMI Sensors division of PCB Piezotronics provides a solution to machine shutdown protection when increased vibration levels signify potential failure.

Models are available in various sizes and include up to eight channels in a single NEMA 4X enclosure. ICP (ICPE) piezoelectric or 4-20 m sensors interface directly with the system, which is universally powered and provides appropriate excitation voltages. Each indicator channel is up to four form C relays for alarm and shutdown control. Time delays and push button programmable settings allow for simple set-up with no false alarms. Indicator lights on the front of each unit display relay status.

According to the company's press release, each meter can integrate an acceleration signal and display the units in acceleration, velocity or displacement on the highly visible bright display.The raw vibration signal can be accessed via BNC connections on the front of the module for easy interface with data collection equipment. Also available is the capability to retransmit a signal for straightforward interface with existing PLC, DCS and SCADA systems.
