4-20 mA Transmitters
Looking for an overall vibration measurement on your most critical machinery? Our line of 4-20 mA vibration transmitters will interface directly to your PLC, DCS or SCADA control system. Scaled in inches per second velocity or g’s acceleration, these sensors provide 24/7online protection for key plant machines, reducing downtime. Finally our impact detection products offer the ultimate machine protection. IMI’s Bearing Fault Detector provides early warning of impending bearing failure from cracks and spalls developing in the bearing race. The Reciprocating Machinery Protector is an impact detector and overall vibration monitor in one 4-20 mA signal.
