Overall vibration sensors and transmitters provide a 4-20 mA signal that can be monitored by today's PLC, DCS and SCADA systems giving users the ability to monitor their most critical machinery 24/7. This is an overall view of IMI's extensive 4-20 mA product line. Choose a link below to zone in on a technology.

IMI offers a complete line of 4-20 mA vibration sensors. As small and as accurate as a piezoelectric accelerometer, these units interface directly to the control system to provide 24/7 vibration levels without breaking the budget: http://www.imi-sensors.com/4-20_mA_Transmitters/Vibration_Transmitters.aspx

Or choose from our complete line of 4-20 mA DIN rail mount signal conditioners and displays featuring our Bearing Fault Detector. Turn your exisiting ICP accelerometers into 24/7 online monitoring devices. IMI's exclusive Bearing Fault Detector allows you to trend not one but two 4-20 mA outputs: overall vibration and outer race ball bearing impact severity: http://www.imi-sensors.com/4-20_mA_Transmitters/DIN-rail_Mount_Modules.aspx

Finally, IMI's Reciprocating Machinery Protector is truely innovative and the first product of its kind. Both an impact and overall vibration transmitter the RMP connects directly to your PLC, DCS or SCADA system and is designed to capture mechanical looseness and cracked rods in receiprocating machinery: http://www.imi-sensors.com/4-20_mA_Transmitters/Reciprocating_Machinery_Protector.aspx 

Coming Soon: Be sure to check back on www.imisensors.com as we release our innovative in-line 4-20 mA vibration converter, model 682A09. This product takes any general purpose industrial accelerometer and converts the signal to a 4-20 mA overall output scaled in velocity.

Bearing Fault Detector
IMI's Bearing Fault Dector (BFD) is used in conjunction with an ICP accelerometer and provides early warning of impending bearing failure. In addition to an overall vibration output the BFD features a second 4-20 mA output scaled for impacts caused by pitting in the housing of rolling-element bearings.

Continuous Monitoring for Critical Machinery
A condensed look at all of IMI's 4-20 mA vibration transmitter options. Vibration transmitters interface directly to a PLC for 24/7 vibration monitoring protection.

Model 649A01 - Reciprocating Machinery Protector
The Reciprocating Machinery Protector (RMP) is both an overall vibration sensor and an impact detector. It provides early warning of impending failure on reciprocating machinery as its peak detection circuitry identifies mechanical looseness.
