In the field of industrial measurement, the NPT100 pressure transmitter, as a key device, directly affects measurement accuracy and system stability through its model selection. This article provides a professional comparison of mainstream models such as DBS316, KL316, and PA1000, helping operators choose the most suitable diffused silicon pressure sensor solution based on actual working conditions such as liquid/gas medium characteristics, alarm control requirements, and remote transmission signals.

I. Technical Principles and Market Status of Diffused Silicon Pressure Transmitters

Diffused silicon pressure sensors realize pressure-electrical signal conversion through the semiconductor piezoresistive effect, with their core advantages being high sensitivity and fast response speed. According to data from the China Industrial Sensor White Paper, the domestic pressure transmitter market reached 4.78 billion yuan in 2022, among which models with intelligent control functions (such as the KL316 alarm control model) achieved a growth rate of 18.3%, significantly higher than traditional models. Based on 10 years of R&D experience, Xi'an Shenghongchuang Instrument Co., Ltd. has developed the NPT series using military-grade silicon chips, with temperature drift controlled within ±0.02%FS/℃, meeting the needs of demanding scenarios such as petrochemicals and water treatment.

II. Functional Comparison of Mainstream Models and Selection Guide

For scenarios requiring local control, it is recommended to use it together with the domestic pressure controller TXZS3 digital pressure controller. This product supports wide-range control from -0.1~100MPa and has passed IP65 protection certification, making it especially suitable for pipeline installation environments with mechanical vibration.

III. Analysis of Common Operation and Maintenance Issues

Misconception 1: All models can measure corrosive media
In fact, standard models such as AP131 need to be equipped with a PTFE diaphragm before they can come into contact with acid and alkali media. According to the requirements of the TXY801 manual, customized models made entirely of titanium should be selected for highly corrosive environments.

Misconception 2: Ignoring the impact of ambient temperature
DT-131 requires derated use in environments above 80℃. It is recommended to refer to the customized solution of XL-802A, whose high-temperature-resistant version can operate stably at 150℃.

IV. Why Choose Shenghongchuang Instrument

• Certified by a national-level laboratory in Xixian New Area, all NPT100 transmitters undergo 72-hour aging tests in accordance with the GB/T 15478 standard before leaving the factory
• Provides the 3D modeling service specified in the YB3101 installation instructions to predict the impact of pipeline vibration on measurement
• Supports the on-site calibration service required by the TCT-1202 manual to ensure long-term accuracy in use
