Process Monitoring & Protection
Process Monitoring & Protection
Vibration monitoring of plant and process machinery can provide crucial data that will lead to increased productivity and profitability. When vibration levels are monitored, excessive wear and potential failure can be recognized.

IMI's line of 4-20 mA vibration transmitters will interface directly to your PLC, DCS or SCADA control system so data can be easily analyzed. Scaled in inches per second velocity or g's acceleration, these sensors provide 24/7 online protection for key plant machines, reducing downtime. IMI's electronic vibration switches and smart switches eliminate false trips, making it a technically superior option to traditional mechanical shock switches, and are a great way to provide protection for your most critical equipment.
Our impact detection products offer the ultimate machine protection. The Bearing Fault Detector provides early warning of impending bearing failure from cracks and spalls. In addition, IMI's DIN rail devices are designed to facilitate vibration monitoring with equipment that is familiar to the process control technician. Signals representing overall vibration levels are monitored with threshold points providing the judgment for alarm, control, or shutdown.
Typical Applications Include:

  Cooling Towers

  Recip. Machinery
  Bearing Condition
