In the field of flow control equipment, the TJH-10 miniature force sensor is gradually replacing traditional models with its innovative design. As a flagship product of Xi'an Shenghongchuang Instrumentation Co., Ltd., this coin-shaped pressure sensor achieves precise measurement with an ultra-small size and is especially suitable for industrial scenarios with limited space. This article will focus on analyzing the three core advantages of the TJH-10 compared with traditional force sensors, providing key decision-making references for technical evaluators.

1. Miniaturized Design Breaks Through Space Limitations

Traditional force sensors such as SSM-LF20 or SSM-LF50 often face installation difficulties in precision flow control systems due to their relatively large size （diameters generally exceed 30mm）. The TJH-10 adopts a coin-shaped structural design, with an outer diameter of only 10mm and a thickness of 6.5mm, reducing space occupancy by 40% compared with similar product SMW-H-3B. This miniature force sensor can be directly embedded into valve actuators or flowmeter feedback units, enabling the following innovative applications:

• Completing radial force monitoring in miniature pipelines below DN15
• Integrating into PLC control modules to achieve in-situ measurement
• Replacing traditional cantilever beam structures to solve mechanical interference issues

According to ISO 376 standard testing, the TJH-10 can still maintain 0.5%FS linearity under a contact area of 5mm×5mm, and this performance indicator has already surpassed traditional models such as SSM-LFC8. For medical devices or semiconductor equipment that require small-sized sensors, its advantages are particularly significant.

2. All-Stainless-Steel Structure Enhances Environmental Adaptability

Compared with sensors with aluminum alloy housings such as PWFC, the TJH-10 adopts 17-4PH precipitation-hardening stainless steel integral forming technology, featuring the following outstanding characteristics:

This design is especially suitable for flow control applications in harsh environments such as the chemical industry and offshore platforms. Actual cases show that the average service life of SSM-LFC10 sensors in coastal oil and gas fields is only 2 years, while under the same working conditions the TJH-10 has operated stably for 4 years without signal drift.

3. Intelligent Compensation Technology Enables High-Precision Measurement

The TJH-10 has a built-in temperature drift self-compensation algorithm, solving the pain points of traditional force sensors through the following technological innovations:

1. Multi-Dimensional Temperature Compensation

It uses three sets of PT100 temperature sensors to monitor the temperatures of the strain gauge, circuit board, and housing in real time, achieving compensation accuracy of 0.01%FS/℃, which is 5 times more effective than the single-point compensation of SSM-LF8.

2. Nonlinear Correction

Based on a neural network algorithm, a load-output model is established to maintain ±0.1% repeatability within the 0-120% range, meeting the requirements of the DIN EN 837 standard for precision force measurement equipment.

3. Anti-Interference Design

The integrated EMI filter can suppress radio frequency interference of 50V/m, and when operating near a frequency converter, the output fluctuation is less than 1/10 of that of the traditional model SMW-H-3B.

4. Verification Through Industry Application Cases

In the flow control system of a large water treatment plant in Shaanxi, the originally used SSM-LF50 sensor had the following problems: limited installation space led to measurement deviations, humid environments caused circuit corrosion, and pump vibration caused signal noise. After replacing it with the TJH-10 miniature force sensor:

• Chemical dosing accuracy improved from ±3% to ±0.8%
• Average annual maintenance frequency dropped from 6 times to 1 time
• System response speed increased by 20%

5. Summary and Selection Recommendations

Through three major innovations—miniaturized design, military-grade materials, and intelligent algorithms—the TJH-10 miniature force sensor provides a better solution for the flow control field. When selecting a coin-shaped pressure sensor, technical evaluators should focus on:

1. The degree of matching between installation space and sensor dimensions
2. The relationship between environmental resistance and expected service life
3. The impact of temperature compensation on long-term stability
