3151智能型压力/差压变送器测量液位使用原理(通译版)

把压力信号传到电子设备,进而在计算机显示压力,其原理大致是:

如将水压这种压力的力学信号转变成电压或电流(一般是0-5V或者4-20mA)这样的电子信号,压力和电压或电流大小成线性关系,一般是正比关系所以,变送器输出的电压或电流随压力增大而增大。

In general, the pressure transmitter often refers to the pressure transmitter and the differential pressure transmitter, which are mainly composed of the sensor of the pressure measuring element, the measuring circuit and the process connection. which can convert the received pressure signals such as gas and liquid into standard current and voltage signals (4~20 mADC) to supply secondary instruments such as indicator alarm, recorder, regulator for measurement, indication and process regulation.

 The pressure transmitter can be divided into general pressure transmitter (-100 Pa~120 MPa) and differential pressure transmitter (0.1~1.5 kPa) according to the range of pressure measurement.
 3151 Intelligent Pressure/Difference Transmitter / Main Role
 The principle of transmitting pressure signals to electronic devices and then displaying pressure on a computer is:
 When a mechanical signal of pressure such as water pressure is converted into an electronic signal such as a voltage or current (usually 0-5 V or 4-20 mA), the pressure and voltage or current are linearly proportional.
 3151 Intelligent pressure/differential pressure transmitter/type
 Range: Micro pressure transmitter, pressure transmitter
 Measurement: differential pressure transmitter, pressure transmitter
 to measurement requirements: absolute pressure transmitter, gauge pressure transmitter, relative gauge pressure transmitter.
