Introduction

In the field of industrial automation, the accuracy and reliability of miniature force sensors directly affect production quality. Centered on the CFBH series miniature force sensors, this article presents measured data from 3 typical industrial scenarios to demonstrate the outstanding performance of coin-type pressure sensors such as EVT-14 and NOS-W401 in confined spaces, providing key selection references for technical evaluators.

Scenario 1: Force Monitoring on Precision Assembly Lines

In the precision assembly process of electronic components, the CFBH miniature force sensor is integrated into the automatic screw-locking workstation. Its coin-type design with a diameter of only 15mm (meeting the same size standard as NOS-W401) is successfully embedded into the limited space of the robotic arm end effector. Measured data shows:

• Within the 0-50N range, linearity error ≤±0.3%FS
• Under high-frequency impact at 60 times per minute, the RSW10B series sensor still maintains repeatability accuracy of 0.5%
• Temperature drift coefficient <0.01%/℃ (referencing the military-grade temperature drift standard of HDW209)

This solution solves the installation interference problem caused by the oversized volume of traditional force sensors, while also enabling seamless integration with PLC systems through the CAN bus output of the CFBHM model.

Scenario 2: Sealing Force Detection of Miniature Pump Valves

In the sealing performance test of miniature diaphragm pumps for medical equipment, the NOS-F305 sensor, with an ultra-thin thickness of only 3mm, is directly installed between the valve seat and the diaphragm. Key data performance:

1. Within the 0-20N micro-force measurement range, the resolution reaches 0.01N
2. After a long-term stability test (2 million cycles), zero drift is <0.1%FS
3. IP67 protection rating (same specification as RSW13) ensures reliable operation in liquid environments

This application verifies the special adaptability of coin-type pressure sensors under humid and confined working conditions, and its stainless steel material and sealing process are consistent with those of NOS-W406.

Scenario 3: Overload Protection for Robot End Tools

Automotive welding robots use CFBH-M series miniature force sensors, which are directly installed at the welding gun gripper through M3 threads. The measured case shows:

• Successfully captures instantaneous impact force of 0.5ms (peak value 300N)
• Multi-axis resultant force measurement error <1.2% (compared with HDW209 multi-dimensional sensor data)
• Output fluctuation <±0.5% within the wide temperature range of -20℃~85℃

This solution significantly reduces the equipment damage rate caused by workpiece positioning deviation, and its compact structural design inherits the core advantages of the small-size sensors in the CFBH series.

Summary and Selection Recommendations

Through validation in the above industrial scenarios, CFBH and its derived series miniature force sensors demonstrate three core advantages:

1. Space adaptability: Coin-type pressure sensors with diameters of 8-25mm can be embedded into the vast majority of mechanical structures
2. Dynamic performance: Millisecond-level response of models such as EVT-14 meets the requirements of high-speed operating conditions
3. Environmental resistance: Protection design at the RSW13 level handles complex environments such as oil contamination and humidity

As a national high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd.'s sensor products have passed ISO9001:2015 quality management system certification. Technical evaluators can select product series such as CFBH, NOS, or RSW according to the force range, sampling frequency, and installation space of specific application scenarios.
