Miniaturized Design Breaks Through Space Limitations

Against the backdrop of continuously increasing integration in industrial automation equipment, the size of traditional pressure sensors often becomes a bottleneck in system design. With a compact structure of 14mm in diameter and 6.5mm in thickness, the NOS-W401 coin-type pressure sensor achieves a smaller space footprint than standard M5 threaded mounting holes. This miniaturized feature makes it particularly suitable for scenarios with stringent installation space requirements, such as embedded medical robot joints and precision pneumatic valve assemblies.

Compared with the EVT-14 load cell of the same category, the NOS-W401 reduces its external dimensions by 18% through optimized strain gauge layout while maintaining the same measuring range (optional from 0-5N to 0-1kN). Its aluminum alloy housing is manufactured using aerospace-grade CNC machining technology, ensuring structural strength while achieving an ultra-light weight of 9 grams, effectively avoiding inertial interference with the measured system.

Comparison of Key Technical Parameters

0.1%F.S High-Accuracy Measurement Performance

Using original imported German HBM strain gauges and full-bridge temperature compensation technology, the NOS-W401 series can achieve a static accuracy of ±0.1%F.S within the operating range of -10℃~80℃. Its non-linearity, hysteresis, and repeatability indicators all meet the ISO376 standard Class 00 requirements, satisfying the accuracy standards for force monitoring in FDA certification of medical devices.

Actual test data show that under a 500N range, this sensor can stably detect tiny force changes of 0.05N, a feature that makes it outstanding in micro-force detection scenarios such as filling accuracy control in the pharmaceutical industry and semiconductor wafer dicing. When used with the CFBHM series signal conditioner, the overall system accuracy can be further improved to 0.05%F.S.

Typical Application Scenarios

• Medical equipment: force feedback system for surgical robot end effectors
• Industrial automation: torque control on 3C product assembly lines
• Energy sector: stacking pressure monitoring of fuel cell stacks
• Scientific research instruments: material mechanical property testing platforms

Environmental Adaptability and Reliability Design

For complex industrial site working conditions, the improved NOS-W406 model adopts an IP67 protection rating design, capable of withstanding oil contamination, dust, and intermittent liquid splashing. Its core sensing element has passed 2 million fatigue tests (according to the JJG391-2009 regulation), and can still maintain long-term stability in an 85%RH high-humidity environment. Compared with traditional models such as HDW209, its mean time between failures (MTBF) has increased to 50,000 hours.

The specially designed anti-electromagnetic interference circuit can effectively suppress 20V/m radio frequency interference generated by equipment such as frequency converters and servo motors, ensuring the reliability of data acquisition in Industrial 4.0 smart factory environments. The product has passed CE and RoHS certifications, and complies with the EN 61326-1:2013 electromagnetic compatibility standard.
