Inline Vibration Transmitter from PCB

PCB Piezotronics Inc., IMI Sensors Div.

The Model 682A09 from PCB Piezotronics Inc., IMI Sensors Div., Depew, NY, is a vibration transmitter that installs inline with any industrial accelerometer and converts the vibration signal to a 4–20 mA velocity output. The SS, hermetically-sealed device installs right into the cable run and can operate in harsh environments with a 2-pin MIL connector input and 3-pin MIL connector output. It accepts a 100 mV/g analog signal and operates off of loop power supplied by the PLC, DCS, or SCADA system. The transmitter also outputs the 100 mV/g signal via its 3-pin output connector, allowing the analog signal to be run to a central collection point, maintaining the FFT capability of the original system.
