PhoQtek offers a broad selection of 4-20 mA vibration transmitters. Our 4-20 mA sensors are an accelerometer and vibration transmitter combined in a rugged industrial housing. They provide a 4-20 mA output signal proportional to the overall vibration level. The 4-20 mA output is commonly accepted by process control systems such as a PLC, DCS or SCADA system for cost-effective continuous vibration monitoring.
