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 continuous monitoring system.
