In the field of industrial automation, the KGY-KGY50 pressure transmitter has become the preferred choice for many enterprises by virtue of its outstanding diffused silicon liquid and gas pressure sensor technology. Faced with different specifications and models, how should you choose the product that best suits your industrial application needs? This article will provide a detailed comparison of the technical parameters, accuracy grades, and measurement ranges of the KGY-KGY50 series to help business evaluators make informed decisions.

I. Core Technology and Industry Background of KGY-KGY50 Pressure Transmitters

As the core component of the KGY-KGY50 series, the diffused silicon liquid and gas pressure sensor adopts advanced MEMS micro-electro-mechanical system technology and achieves high-precision pressure measurement through the piezoresistive effect of silicon crystals. This technology has passed ISO 9001 quality management system certification and complies with IEC 60770 international standard requirements. In the fields of flow control equipment such as petrochemicals, electric power and energy, and water treatment, the KGY-KGY50 series has become the preferred solution to replace traditional mechanical pressure gauges due to its wide operating temperature range of -40℃~125℃ and high accuracy performance of 0.1%FS. Based on 15 years of sensor R&D experience, Xi'an Shenghongchuang Instrumentation Co., Ltd. has carried out 7 technical iterations on the KGY50 series, enabling it to reach an industry-leading level in electromagnetic interference resistance and long-term stability.

II. Comparison of Key Parameters and Selection Guide

For water treatment projects that require long-term monitoring of pipeline pressure, it is recommended to choose the KGY50-10 model, whose 316L stainless steel isolation diaphragm can effectively resist chloride ion corrosion; while in high-pressure water injection systems in the petroleum industry, the 40MPa range and HART communication function of KGY50-40 can meet remote calibration requirements. It is worth noting that all models adopt an IP67 protection rating design to ensure stable operation in harsh industrial environments such as humidity and dust.

III. Typical Application Scenarios and Troubleshooting Solutions

At natural gas transmission and distribution stations, the KGY-KGY50 series pressure transmitters accurately monitor the outlet pressure of the regulator and transmit data to the SCADA system in real time. When the common zero drift problem occurs in the YM-MHQ model, it can be handled through the following steps: first disconnect the power supply and use a standard pressure source for three-point calibration; if the problem persists, check whether the sensor diaphragm is blocked by particulate matter. The PT-BHT calibration toolkit provided by Xi'an Shenghongchuang includes a 0.05 grade standard pressure generator, enabling fast on-site calibration. Actual cases show that after a provincial gas company adopted the KGY50-0.5 model, annual maintenance costs were reduced by 37%, thanks to the product's built-in temperature compensation algorithm and mechanical life design of 100,000 pressure cycles.

IV. Why Choose Xi'an Shenghongchuang's KGY Series

As a national high-tech enterprise, we provide full-process services ranging from M514X-C21162-250BG wiring diagram guidance to PT-PT83 measurement range customization.
