Supply standard torque reference for micro motor calibration, tiny reducer efficiency inspection and small rotary equipment closed-loop control. Detect abnormal overload torque, upload alarm signals to PLC and activate automatic overload protection stop of equipment. Ultra-compact flange integrated structure for easy assembly, ideal for micro motor test benches and lightweight robot joint modules. Low temperature drift and outstanding anti-interference performance, maintaining stable measurement under long-time continuous rotation. 3.Working Principle This transducer adopts foil strain gauge piezoresistive torsion measurement technology: Rotational torque twists the alloy elastic body and generates tiny reversible torsional deformation. Strain gauges attached to elastic body produce resistance changes proportional linearly to torque value. Built-in full Wheatstone bridge converts resistance variation into weak analog voltage signals. External signal conditioning circuit implements temperature compensation, amplification and filtering, and outputs standard torque signals for system acquisition and analysis. 4.Application Scope Applicable Equipment Micro motor test benches, miniature gear reducer testers, tiny robot joint drive modules, portable micro torsion testing tools Matching Components Automation PLC, torque display meter, micro motor drive control module Application Scenarios Micro motor output torque detection, precision small transmission efficiency testing, miniature robot joint torsion monitoring, micro electronic product torsion fatigue testing
