In the field of industrial automation, the selection of the diffused silicon sensor for the TMS-GH186 pressure transmitter is particularly critical. As a core product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this model is widely favored for its high accuracy and stability. This article will provide a detailed interpretation of its specification model parameters, helping you understand the working principle, accuracy class, and common fault handling of diffused silicon sensors, and providing professional reference for the selection of pressure transmitters such as the PTS series, AO-X, and ZFBY3801.

Analysis of Core Diffused Silicon Sensor Technology

The diffused silicon pressure sensor adopts the piezoresistive effect principle of semiconductor silicon materials. When external pressure acts on the sensitive element, its resistance value changes linearly. TMS-GH186 uses a single-crystal silicon chip to form a Wheatstone bridge structure through ion implantation technology, featuring high sensitivity and low temperature drift. Compared with traditional ceramic capacitive sensors, its response speed can be increased by more than 30%, making it particularly suitable for scenarios in industries such as electric power and petrochemicals that require high dynamic pressure monitoring. It is worth noting that the domestically produced capacitive pressure transmitter JSRY-3851 digital display transmitter intelligent differential pressure transmitter also performs excellently in static pressure measurement, and the two form a complementary technology combination.

Comparison of Key Performance Indicators

Practical Selection Guide

When selecting pressure transmitters such as YH-A or BP-IN, the following factors should be considered first: first is media compatibility, for corrosive media, a Hastelloy diaphragm should be selected; second is accuracy requirements, process control usually requires an accuracy of 0.2 class or above; finally is environmental adaptability, explosion-proof applications require models certified with Exd. The TMS-QY110 series provided by Xi'an Shenghongchuang Instrumentation is particularly suitable for the food and pharmaceutical industries, and its hygienic flange design complies with 3A standards.

Typical Fault Handling Solutions

• Zero drift issue: check whether liquid has accumulated in the pressure guide tube, and carry out zero calibration regularly
• Unstable output signal: troubleshoot power supply interference, and ensure the grounding resistance is less than 4Ω
• Diaphragm damage: avoid pressure spike impact, and install a pulse damper

In-Depth Analysis of Industry Applications

In high-temperature scenarios in the metallurgical industry, TMS-GH186 can operate stably in an 800℃ environment with a special heat dissipation structure. For the explosion-proof requirements of the petrochemical industry, these can be met through intrinsically safe circuit design, in compliance with IECEx standard requirements. It is worth noting that the JSRY-3851 series performs excellently in differential pressure measurement in power plant desulfurization systems, and its unique self-cleaning flange design effectively prevents slurry blockage.
