Background

The pressure transmitter is a pressure sensor which takes output as a standard signal, and is an instrument which receives a pressure variable and converts the pressure variable into a standard output signal in proportion. The pressure sensor can convert physical pressure parameters of gas, liquid and the like sensed by the pressure element sensor into standard electric signals (such as 4-20 mADC and the like) so as to supply secondary instruments such as an indication alarm instrument, a recorder, a regulator and the like for measurement, indication and process regulation. When pressure directly acts on the surface of the measuring diaphragm, the diaphragm generates tiny deformation, a high-precision circuit on the measuring diaphragm converts the tiny deformation into a voltage signal which is highly linear and is in direct proportion to the pressure and excitation voltage, and then a special chip is adopted to convert the voltage signal into an industrial standard 4-20mA current signal or 1-5V voltage signal. The measuring diaphragm adopts a standard telephone integrated circuit, and the inside of the measuring diaphragm contains a linear and temperature compensating circuit, so that the high precision and the high stability can be realized, the transmitting circuit adopts a special two-wire chip, some water pressure and process control have pressure peaks or continuous pulses, the pressure peaks can reach 5 times or even 10 times of the maximum pressure, the damage of the transmitter can be caused, the continuous high-pressure pulses are close to or exceed the maximum rated pressure of the transmitter, and the practical service life of the transmitter can be shortened.
