4-20mA Output Pressure Sensors

Choose from an extensive range of pressure with a 4 to 20 milliamp current output signal. These sensors provide a dc current signal which can be used over a long distance without signal degradation.  4-20mA is a staple analogue signal type for process equipment installations where the pressure reading is fed back to a central PLC or other type of control instrumentation.
