Still troubled by the obscure and hard-to-understand TMS-QY110 pressure transmitter manual? This article will help you master the operating essentials of the diffused silicon Haisman pressure sensor in 5 minutes, covering key operational points such as wiring diagrams, troubleshooting, and accuracy calibration. The expert team at Xi'an Shenghongchuang Instrumentation has specially prepared this practical guide to help you quickly get started with industrial-grade pressure monitoring equipment.

Analysis of the Working Principle of the Diffused Silicon Haisman Pressure Sensor

The core of the diffused silicon Haisman pressure sensor lies in its use of the piezoresistive effect of semiconductor silicon material. When external pressure acts on the sensor diaphragm, the resistance value of the silicon crystal changes linearly, and this tiny resistance change is converted into a standard electrical signal output through a Wheatstone bridge. The TMS-QY110 model specifically uses a 316L stainless steel isolation diaphragm, combined with laser trimming temperature compensation technology, ensuring long-term stability of ±0.2%FS/year within the operating temperature range of -40～85℃. This design principle enables it to accurately measure pressure changes within the range of 0～200m water column even under harsh working conditions such as petroleum and chemical industries, and it has the same industrial-grade reliability as the diffused silicon technology used in the Domestic Liquid Level Transmitter PPM-TD Fire Water Tank and Reservoir Liquid Level Sensor.

Key Operation Guide and Troubleshooting

In actual operation, special attention should be paid to three points: wiring must refer to the BP-IB model standard wiring diagram, and incorrect polarity of the 24VDC power supply will trigger the protection circuit; zero-point calibration must be adjusted through the potentiometer under no-load conditions, and if the common 4mA offset of the YH-A model occurs, it is necessary to check whether the diaphragm is crystallized and blocked; routine maintenance should regularly follow the BP-IF verification procedure, using a standard pressure source to verify 0.5 class accuracy. Among common faults, abnormal 20mA full-scale output of the BP-IN model is caused in 90% of cases by diaphragm deformation due to overload pressure exceeding 150%FS, in which case the sensor element needs to be replaced.

Expansion of Industry Application Scenarios

In urban water supply systems, ZFBY-ZFBY3801 and PPM-TD often form a dual-redundancy monitoring network, with the former measuring pump station outlet pressure and the latter monitoring reservoir liquid level, jointly ensuring stable water supply pressure. Power plants, on the other hand, prefer to use TMS-GH186 for steam pipeline pressure monitoring, and its three-level lightning protection module can resist electromagnetic interference from substations. It is worth noting that in crystallization-prone environments such as wastewater treatment plants, the anti-clogging design of the BP-IE model combined with polyurethane wiring can significantly extend the service life of the sensor.
