III. Function and Principle

Core Function: Measures tension, compression, and weight; converts mechanical force into an electrical signal for use in weighing, force measurement, overload protection, and tension control applications.

Principle: Based on the principle of electrical resistance strain gauges. When subjected to force, the sensor's elastic body deforms; this deformation causes a change in the resistance of the strain gauges, which is then processed through a Wheatstone bridge circuit to output a millivolt-level signal directly proportional to the applied force. IV. Applicable Equipment (Primarily Construction Machinery)

Excavators, Loaders, Bulldozers: Weighing, Bucket Capacity Measurement, Torque Limitation

Tractors, Agricultural Machinery: Suspension System Force Measurement, Traction Force Monitoring

Hopper Scales, Platform Scales, Belt Scales: Industrial Weighing

Testing Machines, Tensile Testers: Materials Mechanics Testing

Others: Cranes, Port Machinery, Automation Equipment

VI. Installation and Troubleshooting

Installation Guidelines

Secure both ends via threaded connections; ensure proper alignment to apply force axially and avoid lateral forces.

Ground the cable's shielding layer; keep the cable away from sources of strong electromagnetic interference.

Handle with care; avoid dropping, striking, or subjecting the sensor to overload.

Common Faults

No Signal / Unstable Signal: Broken cable wire, loose connector, damaged strain gauge.

Zero-Point Drift: Temperature fluctuations, installation-induced stress, sensor fatigue.

Output Too Low / Too High: Abnormal excitation voltage, incorrect wiring, damage caused by overload.

Simple Testing Procedures

Zero-Point Output (No Load): Should be close to 0 mV.

Sensitivity Check (Under Load): At a load of 1 ton, the output should be approximately 2 mV/V × Excitation Voltage.
