YSG series inductive pressure transmitterDetailed product description：

Usage Description

The YSG series inductive pressure transmitter can directly indicate the pressure value of the measured medium on site in the production process, and convert the pressure value into a standard DC electrical signal, which is transmitted to the secondary instrument. It has the advantages of intuitiveness, stability, and reliability. Widely used in the production process of various industrial sectors for pressure measurement and signal transmission of liquids, gases, or vapors, to achieve detection and automatic control and regulation of the production process.  

Structural principle
The instrument consists of a mechanical indicator pressure gauge, a converter, and an electronic amplifier. The shell is a splash type structure with good sealing performance, which can protect the internal components from dirt invasion.  
When the pressure of the measured medium is introduced into the spring tube, elastic deformation displacement occurs. When the tube end is displaced, on the one hand, it is amplified by the transmission mechanism, and the pressure value is indicated on the dial by the indicator device. At the same time, through the displacement rod, the iron core inside the inductance coil is driven to change its position, so that the inductance of the inductance coil changes. It is converted into a DC voltage signal through the electronic circuit, and then converted from voltage current to DC current signal. After amplification by the electronic amplifier, it is output.

Overall dimensions
YSG-02, 03 Inductive Micro Voltage Transmitter
Inductive pressure (micro pressure) transmitters are mainly suitable for pressure or negative pressure in industrial production processes and measurement systems for various non crystalline and non solidifying fluid media that do not corrode steel or iron and their alloys. This instrument can convert the pressure value of the measured medium into a standard DC current signal for long-distance transmission of measurement values, and can ultimately be matched with secondary instruments in the central control room to achieve automatic detection and control of the production process. It also has the characteristic of mechanical pointers directly indicating pressure values for on-site process inspection and calibration.
