Working Principle

1. External tension or compression load acts on two end threaded joints of S-beam sensor body;
2. Mechanical elastic deformation occurs on beam central neutral axis, strain gauges attached to beam surface produce proportional resistance change corresponding to load magnitude;
3. Four strain gauges form full Wheatstone bridge circuit, converts tiny resistance variation into differential mV/V analog output signal under stable excitation voltage;
4. External signal amplifier or Chatillon digital force meter collects bridge output signal, calculates and displays real-time force value, peak force and pass/fail test results;
5. Hermetic nitrogen-filled cavity isolates strain gauge from ambient humidity and corrosive gas to maintain long-term measurement stability.

Function Features

• Bidirectional tension and compression dual measurement function, single sensor completes pull and push force testing

4. Compact S-beam form factor easy to integrate into automated test fixtures, assembly presses and packaging equipment;
5. Long-term stable zero drift, no frequent on-site recalibration required under continuous production operation;
6. Standard mV/V analog signal universal compatibility with all industrial force data acquisition systems.

Applicable Industries

Automotive component assembly force testing, electronic product connector insertion force test, packaging sealing tensile test, plastic material tensile/compressive mechanical laboratory testing, medical device assembly force inspection, battery pole crimp force measurement, hardware spring load testing.

Installation Requirements

1. Mounting threaded joints must use spherical self-aligning fixtures to eliminate side load and torque acting on sensor body; side load generates permanent measurement error;
2. Excitation voltage must maintain stable DC 10 V ±0.05 V; unstable power supply causes reading fluctuation;
3. Signal cable routing separated from high-current AC power cables by minimum 30 cm distance to avoid electromagnetic noise interference;
4. Cable compression gland must be fully tightened to maintain IP65 waterproof sealing performance;
5. Sensor body must avoid direct welding, drilling or mechanical machining after factory calibration; machining voids calibration certification;
6. Vertical installation preferred for long-term continuous compression load measurement to avoid cable weight pull zero drift.

Usage Precautions

• Forbid impact load striking sensor body; instantaneous impact exceeds elastic recovery limit and permanently damages strain gauge;
• Do not apply torque or lateral side force to end threaded mounting joints; side load causes irreversible beam deformation;
• Ambient temperature exceeding +70°C continuous operation accelerates strain gauge insulation aging and increases zero drift;
• Signal cable cannot be extended over 10 m without matched signal amplifier; long cable resistance attenuates bridge output signal;
• Avoid chemical solvent splashing on sensor body surface; strong acid/alkali corrodes stainless steel welded sealing seams;
• Annual NIST traceable calibration mandatory to maintain measurement accuracy compliance for quality control records.
