The concept and function of pressure transmitter

The pressure transmitter is to convert the pressure into an electric wireless transmission data enhancement alarm device or a video recorder, etc. It plays a key role in industrial production. The pressure transmitter is mainly composed of three parts, and its pressure is positively correlated with the amount of current. Therefore, when the pressure expands, the current flow of the pressure transmitter will also increase. 1 Overview: The pressure transmitter in the general practical sense is mainly composed of three parts: the pressure measuring component sensor (also called the pressure sensor), the accurate measurement power circuit and the whole process enhancement. It can convert the main parameters of physical pressure such as gas and liquid sensed by the sensor of the pressure measuring components into standard electronic signals (such as 4~50mADC, etc.) to provide secondary instruments such as indicating alarms, video recorders, and controllers. The discs carry out precise measurements, indications and adjustments throughout the process. 2 Definition The pressure transmitter is a kind of instrument panel that accepts the independent variable of pressure. After the sensor is transformed, the pressure change is transformed into a standard output data signal according to a certain proportion. The output data signal of the smart transmitter is sent to the main control room for pressure indication, recording or manipulation. Three-category pressure transmitters can be divided into general pressure transmitters (0.001MPa ~ 35MPa), microplate flowmeters (0 ~ 1.8kPa), and negative pressure intelligent transmitters according to the detection range; from the perspective of accuracy In other words, because our country's base accuracy is 0.5%. Therefore, in recent years, it can be divided into high-precision pressure transmitters (0.1% or 0.2% or 0.075%) and general pressure transmitters (0.5%). The transmitter transmits the pressure data signal to the electronic product, thereby indicating the pressure in the electronic computer. u200d
