In-Line 4-20 mA Vibration Transmitter
May 18, 2010
The transmitter installs in line with any industrial accelerometer and converts the vibration signal to a 4-20 mA velocity output that can be trended with today’s PLC, DCS or SCADA control room systems. Its sleek design installs right into the cable run, no DIN rails, cabinets or special power required. Take existing accelerometers and turn them into 24/7 vibration monitoring devices for the most critical machinery. The unit is a stainless steel, hermetically sealed design capable of operating in the harshest environments, according to the manufacturer, with 2-pin MIL connector input and 3-pin MIL connector output. It accepts a 100 mV/g analog signal, converts to 4-20 mA output and operates off of loop-power supplied by the PLC, DCS or SCADA system. In addition, the transmitter outputs the 100 mV/g analog signal via its 3-pin output connector. The analog signal can be run to a central collection point, allowing the user to maintain the FFT capability of the original system.
