TOP10 ranking of diffused silicon Haisman pressure sensor manufacturers in 2023 is officially released! Xi'an Shenghongchuang Instrument Co., Ltd. has made the list strongly with star products such as the YM-1JY pressure transmitter. This article will provide an in-depth analysis of the principles, installation methods, and maintenance essentials of diffused silicon Haisman pressure sensors, and reveal the technical parameters and selection guide for popular models such as HBP-800D and SP-112G, helping technical evaluators achieve precise model selection.

I. Technical principles and core advantages of diffused silicon Haisman pressure sensors

Diffused silicon Haisman pressure sensors adopt the piezoresistive effect principle of semiconductor silicon materials, and form a Wheatstone bridge structure on the silicon wafer surface through MEMS technology. When external pressure is applied, the silicon diaphragm deforms, causing resistance changes, and the signal conditioning circuit outputs standard 4-20mA or RS485 signals. Compared with traditional strain gauge sensors, its sensitivity is increased by 5-8 times, and its long-term stability reaches ±0.1%FS/year, making it particularly suitable for high-pressure and high-frequency response application scenarios in flow control equipment. The YM-1JY pressure transmitter developed by Xi'an Shenghongchuang uses a military-grade diffused silicon chip, has passed ISO9001/TS16949 dual-system certification, and maintains ±0.25% accuracy performance within the wide temperature range of -40℃~125℃.

III. Typical application scenarios and installation specifications

In petrochemical process control, the SP-112G pressure transmitter can stably monitor pipeline pressure fluctuations by virtue of its IP67 protection rating and intrinsic safety certification. During installation, note that: 1) polytetrafluoroethylene sealing tape should be used for threaded connections; 2) avoid applying mechanical stress to the sensor body; 3) the cable entry should face downward to prevent condensate accumulation. For the TPT-TPT503 model with alarm control, technical evaluators need to specifically verify whether the setpoint range matches the process requirements, and zero-point calibration is recommended every 6 months.

IV. Maintenance and troubleshooting guide

• Routine maintenance:Check the oxidation condition of the wiring terminals of the JN-8001 pressure transmitter every month, and clean the measuring diaphragm with anhydrous ethanol
• Signal anomaly handling:If the CPS-CPS2016 model shows remote transmission signal fluctuations, first check the stability of the 24V power supply and the grounding resistance
• Winter protection:The PRC-905 transmitter needs to be equipped with heat tracing tubing in low-temperature environments to prevent medium crystallization
