2-Wire Vibration TransmitterSTI Vibration Monitoring’s 4-20mA sensors are an accelerometer and transmitter combined into one housing. Each sensor provides a 4-20mA output signal proportional to the overall vibration level in terms of acceleration, velocity or temperature. 4-20mA sensors can interface directly with process control systems such as PLC, DCS and SCADA systems creating a low cost and effective continous monitoring system. All 4-20mA sensors are approved for use in Class 1 Division 2 areas or Class 1 Division 1 with an approved barrier. STI keeps all popular models in stock for immediate delivery.
