As the core product of diffused silicon liquid and gas pressure sensors, the HTJ-HTJ100 pressure transmitter has attracted extensive industry attention for its precise measurement principle. This article provides an in-depth analysis of the working principle of the HTJ-HTJ100, helping you understand how this high-performance pressure transmitter achieves stable and reliable pressure detection through advanced diffused silicon technology, and enabling operators to better grasp equipment characteristics and maintenance essentials.

I. Detailed Explanation of the Principle of Diffused Silicon Pressure Sensing Technology

The HTJ-HTJ100 pressure transmitter uses the piezoresistive effect of semiconductor diffused silicon as its core measurement principle. When external pressure acts on the sensor diaphragm, the resistance value of the Wheatstone bridge embedded in the silicon crystal changes linearly, and this change is converted into a 4-20mA standard signal output through precision circuitry. Compared with traditional strain gauge technology, diffused silicon sensors offer significant advantages such as high sensitivity (typical value up to 2mV/V), low temperature drift (±0.5%FS/℃), and good long-term stability (±0.1%FS/year). Through special ion implantation processes and temperature compensation algorithms, Xi’an Shenghongchuang Instrumentation Co., Ltd. enables the HTJ-HTJ100 to maintain high accuracy of 0.25%FS within the wide temperature range of -40℃~125℃.

III. Typical Fault Handling and Maintenance Guide

For common zero drift issues in equipment such as the KYB-800 pressure transmitter, the HTJ-HTJ100 achieves automatic compensation through three-point laser calibration technology. When abnormal output occurs, operators should first check: 1）whether the power supply voltage is stable at 24VDC±10%；2）whether the wiring terminals are oxidized (refer to the waterproof treatment solution in the LD-108-3PBA793 manual)；3）whether there is medium crystallization at the process connection. The DG1300-BZ series display instruments provided by Xi’an Shenghongchuang can directly read the sensor health status, and together with the SK-DBS316E1ERC2L-2m calibration kit, accuracy verification can be completed on site, greatly reducing downtime.

IV. In-Depth Analysis of Application Scenarios for Selection

In the petrochemical field, corrosive medium measurement solutions for models such as PT124B-210-1MPa-G1/2 often face challenges. The tantalum diaphragm optional version of the HTJ-HTJ100 can withstand harsh environments with H2S content up to 5000ppm, and its fast response characteristic （＜1ms） can better meet the dynamic pressure monitoring requirements of the SMP131-TLD-L105GS-D1-F-53-4G15 model in hydraulic systems. For the food and pharmaceutical industries, the hygienic design of the NS-I pressure transmitter is also applicable to the HTJ series, ensuring dead-zone-free cleaning through a 3-A certified Tri-Clamp connection.
