  • Product Introduction
    This product is widely used in water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields to realize the measurement of liquid, gas, and vapor pressure.

Working principle

The intelligent pressure transmitter is an advanced pressure measurement and signal conversion device with intelligent and multifunctional characteristics. It converts the pressure of the medium to be measured into a standard electrical signal output and offers a variety of additional functions and intelligent features.


When the pressure directly acts on the surface of the measuring diaphragm, the diaphragm produces a small deformation. The high-precision circuit on the measuring diaphragm transforms this small deformation into a highly linear voltage proportional to the pressure and proportional to the excitation voltage. Signal, and then use the chip to convert this voltage signal into an industry standard 4-20mA current signal or 1-5V voltage signal.

Since the measuring diaphragm adopts standard integrated circuits and contains linearity and temperature compensation circuits inside, it can achieve high precision and high stability. The two-wire chip used in the transmission circuit can ensure the output of a two-wire 4-20mA current signal.


Product Features

The pressure transmitter selects sputtering thin film sensor, imported silicon diffusion type, ceramic pressure sensor as the sensitive element, and adopts a dedicated integrated module. After fine temperature drift, zero point, and nonlinear compensation, it can realize the control of liquid level, gas, and steam. Accurate measurement and transmission of pressure changes of other media. Realize ideal monitoring of pressure vacuum in various places in industrial and mining enterprises, scientific research institutes and other departments.
