What is the difference between 2-wire transmitter, 3-wire transmitter and 4- wire transmitter? 2-wire transmitter 2-wire transmitters are the simplest and most economical way to used them in the industrial field. The zero-end current is 4mA, which is sufficient to drive the transmitter's internal circuitry, while the current at 4-20mA represents the range of process transmissions measured. 3-wire transmitter Some transmitter require more power than the signal loop can supply their internal circuity. The three-wire current output can share a ground wire with the power supply, saving a wire. 4-wire transmitter Four-wire transmitters have their own internal power supply, and they do not need to be connected to a DC power supply. It has two power cords and two current output lines. The output of a 4-wire transmitter is usually a current signal. We provide kinds of isolated signal conditioner, include pt100 signal conditioner, universal signal conditioner, 24v to 5v signal converter, 5v to 24v plc signal converter and so on.
