The CHSP-210 pressure transmitter adopts German HESMANN diffused silicon technology, featuring core advantages such as high accuracy and strong anti-interference performance, making it an ideal choice for pressure monitoring in industrial automation. This article provides an in-depth analysis of its structural principles, performance parameters, and industry application scenarios, helping you quickly master the key selection points of this critical sensor.

I. Technical Principles of the Diffused Silicon HESMANN Sensor

The diffused silicon pressure sensor is based on the semiconductor piezoresistive effect, forming a Wheatstone bridge structure on the silicon wafer surface through ion implantation technology. When external pressure acts on the sensing element, deformation of the silicon lattice causes resistance value changes, which are converted into a standard 4-20mA output through the signal conditioning circuit. The CHSP-210 adopts HESMANN's patented temperature compensation algorithm and laser trimming technology, achieving high accuracy of ±0.1%FS within the range of -40℃~125℃, significantly outperforming traditional strain gauge sensors.

III. Analysis of Typical Application Scenarios

In the petrochemical field, the CHSP-210, with its Ex ia IIC T6 Ga explosion-proof certification, can be safely used for reactor pressure monitoring; its 316L stainless steel isolation diaphragm can withstand H2S corrosion, delivering outstanding performance in natural gas processing plants. Similarly, the domestic capacitive pressure transmitter WIDEPLUS-AK has also passed IECEx certification and is suitable for harsh environments such as electric power and metallurgy.

IV. Technical Guide for Purchasing and Selection

• Range matching: It is recommended that the working pressure be within the 30%-80% range of the full scale
• Process connection: G1/2" flange or M20×1.5 thread must match the pipeline specifications
• Media compatibility: Fluororubber seals are suitable for most corrosive media
• Output protocol: The HART protocol version must be compatible with the control system
