SSM-LFC8 Coin-Type Pressure Sensor Field Test: Can a Small Size Withstand Industrial-Grade Loads?

In the field of industrial automation, the SSM-LFC8 coin-type pressure sensor has attracted attention for its compact size. As a flagship product of Xi'an Shenghongchuang Instrumentation Co., Ltd., can this miniature force sensor maintain stable performance under harsh working conditions? This article will field-test its load resistance and accuracy performance, providing key decision-making references for technical evaluators.

I. Analysis of Product Design and Technical Parameters

The SSM-LFC8 adopts a coin-type structural design, with a diameter of only 8mm, a thickness of 3.5mm, and a weight of no more than 5g. Its core uses 316L stainless steel material and achieves an IP67 protection rating through laser welding technology. The technical parameters show:

• Measurement range: 0-50MPa（customizable up to 100MPa）
• Non-linearity: ±0.3%FS（after laboratory temperature compensation）
• Operating temperature: -20℃~85℃（extended version up to 125℃）
• Output signal: 2.0mV/V standard bridge output

Compared with similar products such as the SSM-LFC10, its volume is reduced by 40% while maintaining the same range. This high-density packaging technology is particularly suitable for industrial scenarios with limited space.

II. Industrial-Grade Load Testing Plan

We built a test platform compliant with ISO 376 standards, including:

During the testing process, data from the SSM-LFC8 and the reference-grade PWFC sensor were collected synchronously to ensure that the benchmark comparison error was ≤0.05%.

III. Key Performance Field Test Data

In the 72-hour continuous test, the SSM-LFC8 demonstrated the following characteristics:

1. Overload capacity: under 120% rated load, the non-linearity error increased by only 0.12%, far better than the 0.5% limit specified by IEC 60770 standards
2. Long-term stability: after 10^6 dynamic cycles, the zero-point drift was 2.3μcm, equivalent to 0.18% of full scale
3. Temperature effect: within the range of -20℃~85℃, the thermal zero drift coefficient was 0.008%/℃

It is particularly worth noting that its response time is <1ms, 3 times faster than the traditional SMW-H-3B model, which is crucial for high-speed fluid control scenarios.

IV. Validation in Typical Application Scenarios

We deployed the SSM-LFC8 in three actual working conditions:

• Hydraulic system monitoring: under a working pressure of 32MPa, parallel testing with the SSM-LF20 showed a data consistency deviation of <0.15%
• Mechanical arm end force control: integrated into the fingertip of a KUKA robotic arm, successfully detecting a tiny contact force of 0.5N
• Micro pump station diagnostics: successfully identified an abnormal pressure pulsation of 0.8Hz through FFT analysis

Field data show that this sensor can still maintain stable output in an environment with vibration intensity up to 5Grms.

V. Technical Comparison with Competing Products

Mainstream micro sensors on the market were selected for horizontal comparison:

It can be seen that while maintaining the smallest size, the SSM-LFC8 outperforms similar products in all key indicators.

VI. Recommendations for Technical Evaluation

Based on the field test results, we offer the following recommendations to technical evaluators:

• Give priority to this model in scenarios with limited space and requiring high-frequency response（such as servo valve testing）
• For long-term operation in corrosive environments, it is recommended to choose the PTFE-coated version
• When used in combination with larger-sized sensors such as the SSM-LF50, a multi-scale measurement system can be built
