Definition

The Nexisense YD-322 General Pressure Transmitter is a high-precision pressure measurement device developed by Nexisense, designed specifically for industrial automation and process control. It can accurately measure the pressure of various liquids and gases, widely used in industries such as chemicals, petroleum, and food.

Principle

The working principle of the pressure transmitter is based on the physical characteristics of pressure sensors. When the measuring medium is applied to the diaphragm of the transmitter, the diaphragm deforms, and the internal sensor converts this deformation into an electrical signal. Depending on the type of output signal, the transmitter transmits the pressure information to the control system, enabling real-time monitoring and control of pressure.

Structure Analysis

The structure of the Nexisense YD-322 pressure transmitter mainly consists of a diaphragm, sensor, electronic circuit, and housing. The diaphragm is made of 316L stainless steel, which has excellent corrosion resistance and mechanical strength, allowing it to adapt to various working conditions. The internal sensor is responsible for converting the pressure signal into an electrical signal, while the electronic circuit processes and outputs the signal. The housing is made of 304 stainless steel, ensuring the stability and reliability of the transmitter in harsh environments.
