    Types and selection of pressure sensors and pressure transmitters: Pressure sensors and pressure transmitters are divided into gauge pressure, full pressure and differential pressure. Common precision grades such as 0.1, 0.2, 0.5 and 1.0. The measurable pressure range is very wide, as small as tens of millimeters of water column and as large as hundreds of megapascals. The working temperature ranges of different kinds of pressure sensors and pressure transmitters are also different, which are often divided into several grades: 0~70℃, -25~85℃, -40~125℃ and -55~150℃. The working temperature of some special pressure sensors can reach 400~500℃. Pressure sensors and pressure transmitters have different waterproof properties and explosion-proof grades based on different materials and structural designs. Due to the differences in materials and shapes, the types of fluid media that can be measured in the liquid receiving cavity are also different, which are often divided into dry gas, general liquid, acid-base corrosive solution, flammable gas-liquid, viscous and special media. As primary instruments, pressure sensors and pressure transmitters need to be used together with secondary instruments or computers. The common power supply modes of pressure sensors and pressure transmitters are: DC5V, 12V, 24V, 12V, etc., and the output modes are: 0~5V, 1~5V, 0.5~4.5V, 0~10mA.0~20mA.4~20mA, etc., and interfaces with computers such as Rs232 and Rs485. When selecting pressure sensors and pressure transmitters, users should fully understand the working conditions of the pressure measurement system, and make reasonable selection according to the needs, so that the system can work in the best state and the project cost can be reduced. Common precision parameters of pressure sensor and test equipment Static calibration equipment of sensor: piston manometer: accuracy is better than 0.05%; digital manometer: accuracy is better than 0.05%; DC regulated power supply: accuracy is better than 0.05%; sensor temperature inspection equipment: high temperature test chamber: temperature control accuracy is 1℃; low temperature test chamber: temperature can be from 0℃ to-60℃. Sensor environmental test items: zero temperature drift, sensitivity drift, zero hysteresis, sensitivity hysteresis. (Check the adaptability of the product to temperature within the specified temperature range. This parameter is very important to the accuracy.) Precautions for the use of pressure sensors Pressure sensors and pressure transmitters should read the product samples and operating instructions in detail before installation, and the pressure interface should not be leaked during installation to ensure the correct range and wiring. Generally, the housings of pressure sensors and pressure transmitters need to be grounded. Signal cables should not be mixed with power cables, and strong electromagnetic interference should be avoided around pressure sensors and pressure transmitters. Pressure sensors and pressure transmitters shall be periodically verified according to industry regulations in use.
