In the fields of industrial automation and precision measurement, the selection of JLWX miniature force sensors directly affects equipment performance. This article reveals 5 key parameters that are often overlooked, helping you avoid application pitfalls of coin-type compact sensors such as RSW10A and RSW20C. The expert team at Xi'an Shenghongchuang Instrumentation analyzes the selection essentials of miniature force sensors for you.

I. Definition and Industry Applications of Miniature Force Sensors

As core components in the field of precision measurement, the performance of miniature force sensors directly affects the stability of critical scenarios such as flow control equipment and automated production lines. The JLWX series products developed by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopt a coin-type structural design (minimum diameter 15mm), achieving high accuracy of 0.1%F.S in models such as RSW20A and RSW25, meeting the application requirements of space-sensitive industries such as medical devices and semiconductor equipment. It is worth noting that although common sensors on the market such as HDW210 or MCC-W are similar in size, there are significant differences in hidden parameters such as dynamic response frequency (>1kHz) and lateral force interference resistance (<5% error).

II. Analysis of 5 Key Parameters You Must Check When Selecting a Model

1. Nonlinearity Error and Repeatability Accuracy

Technical evaluators often focus on the rated range (such as the 50kg range of RSL15), while overlooking the impact of nonlinearity error (0.03% vs 0.05%) on long-term stability. Measured data shows that after the WTP209 sensor operates continuously for 2000 hours, models with nonlinearity error exceeding 0.1% will exhibit obvious zero drift.

2. Temperature Compensation Range

Temperature fluctuations at industrial sites can cause output drift in miniature sensors such as RSW20B. Through full-scale temperature compensation from -20℃~80℃ (compliant with ISO 376 standard), the JLWX series from Shenghongchuang reduces temperature influence by 40% compared with similar products.

3. Protection Rating and Sealing Performance

Coin-type sensors with IP67 and IP68 protection ratings (such as HDW210) differ by 3 times in failure rate under humid environments. Our tests show that the RSW10A using laser-welded sealing can remain corrosion-free for 500 hours in salt spray testing.

III. Typical Application Misunderstandings of Miniature Force Sensors

Many users mistakenly believe that small-size sensors (such as the RSW20A with a diameter of 20mm) can be installed arbitrarily. In fact, the flatness of the mounting surface must be controlled within 0.01mm, otherwise the measurement error of JLWX series products will increase by 2-3 times. In addition, when miniature weighing sensors such as RSL15 are used in dynamic measurement, special attention must be paid to the matching relationship between their բնական frequency (usually >5kHz) and the vibration source.
