Description

A pressure sensor is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules.
Pressure sensors are usually composed of pressure sensitive elements and signal processing units. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools , pipeline and many other industries. The wiring of sensors has always been one of the most frequently consulted issues in the procurement process of customers. Many customers do not know how to connect sensors. In fact, the wiring methods of various sensors are basically the same. Pressure sensors generally have two-wire, three-wire, Four-wire system, and some have five-wire system.
The two-wire system of the pressure sensor is relatively simple. Generally, customers know how to wire it. One line is connected to the positive pole of the power supply, and the other line is the signal line connected to the negative pole of the power supply through the instrument. This is the simplest, and the three-wire system of the pressure sensor is in two. A wire is added on the basis of the wire system. This wire is directly connected to the negative pole of the power supply, which is a little 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 systems are voltage output instead of 4~20mA output. 4~20mA is called pressure transmitter, and most of them are made into two-wire system. Some of the signal output of the pressure sensor is not amplified, and the full-scale output is only tens of millivolts, while some pressure sensors have an internal amplifier circuit, and the full-scale output is 0~2V.
