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.
