Rack Supported Microprocessor Based Monitor is capable of accepting inputs from Proximity probes, seismic sensors of any make to monitor shaft vibrations, casing vibration values as peak to peak, peak value or RMS value. The Monitor provides analog output in the form of 4-20mA for all the channels and potential free relay contacts for digital output can generate alarm, trip signal when the monitored values exceed a present limit. The Monitor is supported with a rack that can accept input from the Air Gap Sensors also to provide air gap monitoring. Rack Supported Microprocessor Based Monitor comes in different specifications to cater to industrial requirement.
