Vibration Velocity Transmitters are compatible with voltage output accelerometer & velometer sensors and provide a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the vibration signal to determine overall amplitude and outputs a 4-20 mA dc current that is proportional to a user specified range such as 0-0.5 in/sec in peak or RMS detection. They have BNC connector, which is mounted on the front of the unit that provides access to the buffered transducer output signal. These transmitter features DIN rail mount, voltage output accelerometer or velometer input, 4-20 mA output, fault detection and buffered transducer output.
