In the field of precision force measurement, the CXH-127 coin-type pressure sensor stands out with its high accuracy performance of 0.1%. As a flagship product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this miniature force sensor achieves industrial-grade measurement with an ultra-small size, perfectly solving the challenge of force value monitoring in space-constrained scenarios. This article will provide an in-depth analysis of its core technical principles and innovative manufacturing processes.

I. Technical Performance and Parameter Analysis

The CXH-127 coin-type pressure sensor is made of highly stable stainless steel, with a diameter of only 12.7mm, a thickness of 5mm, and a weight of less than 10g, yet it can support a measurement range of 0-50kg. Its core advantages lie in a nonlinearity error of 0.1%FS and a temperature drift coefficient of ±0.05%F.S/℃, a specification that has reached the Class A accuracy standard certified by Germany's PTB. Through a unique full-bridge strain gauge circuit design and laser trimming process, the sensor can still maintain a repeatability accuracy of ±0.3% in environments from -20℃~80℃, far exceeding the industry average of ±1% for similar miniature sensors.

This product adopts an IP67 protection rating design, equipped with M3 threaded mounting holes, and supports multiple output modes such as 4-20mA/0-5V. Particularly noteworthy is its high response frequency of 10kHz, which can capture millisecond-level dynamic force changes, making it irreplaceable in quality inspection on automated assembly lines. Xi'an Shenghongchuang's patented temperature compensation algorithm （Patent No. ZL202010XXXXXX.X） enables real-time calibration through a built-in digital processing chip, solving the temperature drift problem commonly found in miniature sensors.

II. Application Scenarios and Industry Pain Point Solutions

In the medical device field, the CXH-127 has been successfully applied to the force feedback system of surgical robot end effectors. Clinical data from a top-tier hospital shows that after using this sensor, the nerve injury rate in robot-assisted prostatectomy was reduced by 42%. Its miniaturized characteristics perfectly solve the difficulty that traditional force sensors cannot be embedded into robotic arm joints, while also meeting the hygiene standards required for ISO 13485 medical device certification.

In industrial automation, this sensor has achieved 0.01N-level screw fastening force monitoring on 3C product assembly lines. After adoption by a mobile phone manufacturer, the defective rate of screen assembly dropped from 3.2% to 0.5%, saving more than 8 million yuan annually in repair costs. Compared with traditional PLD204D series sensors, the CXH-127 requires 60% less installation space, making it especially suitable for precision assembly of miniature electronic products such as smartwatches.

III. Comparative Analysis and Selection Guide

Business evaluators should focus on the following: 1) the actual measurement range should be selected within 20%-80% of full scale; 2) for vibration environments, the HGLF3 series with mechanical filtering should be selected; 3) for corrosive media, the 316L stainless steel version should be specified.
