The wiring of the sensor has always been one of the most frequently consulted questions in the procurement process of customers.Many customers don’t know how the sensors are connected. In fact, the wiring methods of various sensors are basically the same.Pressure sensors generally have a two-wire system, a three-wire system, a four-wire system, and some have a five-wire system.

The two-wire system of the pressure sensor is relatively simple, and most customers know how to wire it.One wire is connected to the positive pole of the power supply, and the other wire is the signal wire connected to the negative pole of the power supply through the instrument.The three-wire system of the pressure sensor is based on the two-wire system with a line that is directly connected to the negative pole of the power supply, which is a bit more troublesome than the two-wire system.The four-wire pressure sensor must be two power input terminals, and the other two are signal output terminals.Most of the four-wire system is a voltage output instead of 4-20mA output. The 4-20mA is called a pressure transmitter, and most of them are made into a two-wire system.The signal output of some pressure sensors is not amplified, and the full-scale output is only tens of millivolts, while some pressure sensors have an internal amplification circuit, and the full-scale output is 0~2V.As for how to connect to the display instrument, it depends on the range of the instrument.If there is a gear that is compatible with the output signal, it can be measured directly, otherwise a signal adjustment circuit must be added.The five-wire pressure sensor is not much different from the four-wire system, and there are fewer five-wire sensors on the market.
