4–20 mA Process Control Loops

In electrical signalling an analog current loop is used where a device must be monitored or controlled remotely over a

4-20 mA instrumentation and controls usually support a signal range slightly below 4 mA and above 20 mA. For transmitters,

The Loop checking is defined as pre-Commissioning activity which is initiated after installation of instruments in the field and carry out the

The term “loop” can refer to the entire “control loop” from primary element (sensor) through the transmitter, and controller, to
