PT3023 sensor selection is a key link in high-temperature liquid level measurement systems, and its temperature range and media compatibility directly determine the reliability of the equipment under harsh operating conditions. This article provides a professional selection comparison table for high-temperature pressure-guided liquid level transmitter series such as YM-GWYW and DB101G1EE202Z, helping technical evaluators quickly match stainless steel cable-cylinder sensors with the characteristics of high-temperature media, ensuring the accuracy and stability of water level measurement.

I、Definition and Core Parameters of High-Temperature Pressure-Guided Liquid Level Transmitters

High-temperature pressure-guided liquid level transmitters are precision instruments that measure liquid height through the pressure-guiding principle, and their core components include stainless steel cable-cylinder sensors and high-temperature-resistant circuit modules. Taking models such as PT3023 and YM-GWYW produced by Xi'an Shenghongchuang Instrumentation Co., Ltd. as examples, their key technical parameters include: temperature range（-50°C~400°C）, media compatibility（acidity and alkalinity PH value 1-14）, pressure rating（0-10MPa）as well as protection rating（IP68）. These parameters directly determine the adaptability of the sensors in high-temperature and high-pressure environments such as petrochemical and power energy industries.

II、Comparative Analysis of Temperature Range and Media Compatibility

For different industrial scenarios, we have compiled a performance comparison table of mainstream models:

III、Common Technical Misunderstandings in the Selection Process

When selecting models such as YM-BWGYW and HSBG-E7100A2K1W2, many technical evaluators often have the following cognitive deviations: 1）only focusing on the nominal upper temperature limit while ignoring resistance to sudden temperature changes; 2）failing to consider the impact of medium viscosity on the pressure-guiding cavity; 3）underestimating the mechanical fatigue risk of the cable-cylinder structure in vibration environments. Xi'an Shenghongchuang's PCM262 series specially adopts a corrugated tube buffering design, which can effectively solve these problems.

IV、Typical Application Scenario Solutions

In liquid level monitoring of desulfurization towers in thermal power plants, the UDTB model has successfully replaced imported products by virtue of its corrosion resistance（able to withstand strong acid with a PH value of 1）and 400°C high-temperature resistance. Case data shows that its measurement error is controlled within ±0.1%FS, far superior to the ±0.5%FS required by the IEC60770-1 standard.
