Options for the iT Transmitter signal conditioning modules now include four different outputs of r.m.s., peak, true peak and true peak-to-peak; measurement of acceleration, velocity or displacement; and a selectable full scale that can be specified in standard or metric units. âThe iT Series allows maintenance professionals to create a custom vibration monitoring center,â says Tom Smith, director of sales and marketing at the vendor. âEach iT Transmitter is custom-built to user specifications.â The iT vibration transmitter converts vibration sensor signals to proportional 4-20mA output for use in existing PLC/DCS networks, and can operate at much lower or much higher frequencies than typical ISO-standard 4-20mA sensors, the vendor says.
