Performance and Test Analysis of WFS Displacement Sensors in High-Temperature Environments

This article provides detailed testing of the performance of WFS displacement sensors in high-temperature environments，with a focus on evaluating the stability and accuracy of LS88-3002，JS130-5000 and other series of draw-wire electronic rulers. As a professional manufacturer of flow control equipment，Xi'an Shenghongchuang Instrument Co., Ltd. provides reliable selection references for technical evaluators through rigorous test data.

In the fields of industrial automation and process control，the stability and accuracy of displacement sensors directly affect production efficiency and equipment safety. Especially in high-temperature environments，the material performance，signal output stability and mechanical structure reliability of sensors face severe challenges. Based on 20 years of industry experience，Xi'an Shenghongchuang Instrument Co., Ltd. conducted systematic high-temperature testing on the WFS series draw-wire electronic rulers，providing data support for technical decision-makers.

I. Test Environment and Standard Specifications

This test strictly referred to the GB/T 2423.2-2008 environmental testing standard for electrical and electronic products，and an adjustable temperature control chamber of 80℃~200℃ was built. The test objects covered the main models of the WFS series，including LS88-3002，JS130-5000，WYS-M and other draw-wire distance measuring sensors，and 3 sets of parallel experiments were conducted for each product to ensure data reliability.

The test equipment used a high-precision thermal imager imported from Germany（±0.3℃ error）and a laser interferometer（resolution 0.1μm）to monitor the sensor housing temperature and output signal fluctuations in real time. Test items included：

• Temperature drift coefficient test for continuous operation of 100 hours
• Mechanical structure stability under thermal shock cycles（-20℃←→150℃）
• Comparison of linearity errors under different temperature gradients
• Verification of signal transmission anti-interference capability

II. Comparison of Core Performance Parameters

In a 150℃ constant-temperature environment，WFS displacement sensors showed significant advantages. Taking the JS130-5000 draw-wire electronic ruler as an example，its key indicators are shown in the table below：

It is particularly worth noting that the WFM displacement sensor adopts a special alloy housing and ceramic bearing design，and still maintains a linearity of ±0.18% F.S. in the 200℃ limit test，which is 40% better than the industry average.

III. Analysis of Key Technological Innovations

Xi'an Shenghongchuang's WXS displacement sensor series achieves breakthroughs in high-temperature stability through three core technologies：

1. Thermal Compensation Algorithm Upgrade

The built-in temperature sensor collects environmental data in real time，and the output signal is dynamically corrected through a 32-bit MCU. Tests show that the JS80-2000 model controls signal drift within ±0.1% under operating conditions with temperature fluctuations of ±50℃/h.

2. Mechanical Structure Optimization

The draw-wire mechanism adopts a combination of tungsten steel material and self-lubricating graphite bushing. After 2000 thermal cycle tests，the return stroke error of the JS58-1000 displacement sensor remains less than 0.15mm.

3. High-Temperature-Resistant Material System

WX series sensors use a polyimide insulation layer and an alumina ceramic substrate. During continuous operation at 180℃，the insulation resistance remains ＞100MΩ，effectively preventing the risk of high-temperature leakage.

IV. Industry Application Recommendations and Selection Guide

Based on the test data，the following models are recommended for different high-temperature scenarios：

• Steel Continuous Casting Equipment（≤250℃）：WNS displacement sensors are preferred，as their heat-resistant steel housings can withstand instantaneous high-temperature impacts
• Glass Kiln Monitoring（150~180℃）：Select the WYS-M draw-wire electronic ruler，with a protection rating specially optimized for acidic and alkaline environments
• Chemical Reaction Kettles（80~120℃）：The LS88-3002 model is recommended，offering the best cost performance and a maintenance cycle of up to 5 years

For scenarios with drastic temperature changes，it is recommended to add heat dissipation fins or select WFM series products with a forced air-cooling interface.

V. Professional Summary and Technical Outlook

This test proves that Xi'an Shenghongchuang's WFS displacement sensor series can still maintain excellent measurement performance in high-temperature environments. Its core technical advantages are reflected in：materials science innovation（8 high-temperature-resistant patents），intelligent compensation algorithms（error reduced by 62%），and modular design（supporting rapid replacement of wearing parts）.

With the development of Industry 4.0，the next-generation WXS displacement sensor will integrate wireless transmission and predictive maintenance functions. At present，the company has established a joint laboratory with Xi'an Jiaotong University to carry out industrialization research on graphene temperature sensors.
