The BAR-GP1 pressure transmitter achieves an industry-leading accuracy of 0.1%FS through diffused silicon sensor core technology, providing reliable measurement assurance for industrial process control. This article will provide an in-depth analysis of the precise working principles of diffused silicon sensors in CEMPX215-GATCA1, BSCYG9010-1.0 and other series products, helping contract execution personnel accurately select models and optimize pressure monitoring systems.

I. Technical Principles and Accuracy Breakthroughs of Diffused Silicon Sensors

Diffused silicon pressure sensors adopt the semiconductor piezoresistive effect principle, forming a Wheatstone bridge by diffusion on a monocrystalline silicon diaphragm. When the BAR-GP1 pressure transmitter is subjected to external force, the silicon diaphragm undergoes slight deformation, causing resistance changes, and after temperature compensation and signal amplification, outputs a standard 4-20mA signal. Compared with traditional ceramic capacitive sensors, its sensitivity is increased by 5-10 times, enabling models such as KYB-Z04 and CS-PT1200V to achieve ultra-high accuracy of ±0.1%FS, making them especially suitable for fields with stringent measurement requirements such as petrochemicals and pharmaceuticals.

II. Key Parameter Comparison and Selection Guide

When selecting models such as EDYBT-49 and HQ-HQ1002, contract executors need to focus on the following parameters:

III. Typical Fault Handling and Calibration Specifications

Common faults of the ZWP-L61-K pressure transmitter include zero drift and unstable output signals, which can usually be checked through the following steps:1) Check whether the power supply voltage meets the 24VDC±10% requirement;2) Use a HART communicator to recalibrate the range;3) Confirm that there is no leakage at the process connection. According to the GB/T 17614.3-2015 standard, it is recommended to perform full-range calibration on models such as CFUEIIIERC1 every 12 months to ensure that measurement accuracy continues to meet standards.
