Overview
The MK902-C is a torque sensor intended for static and non-continuous rotation applications, where a reaction shaft or slowly turning member must be measured and controlled rather than monitored at speed. It combines good accuracy with stable output and simple mounting, so it suits bench and assembly use as readily as in-plant checks.
Key Features
- For static and intermittent rotation torque
- Stable output with straightforward installation
- High accuracy (±0.1 / 0.3%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Standard output 1.0-2.0mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Used for static torque measurement and control in assembly, bolt-tightening and test-rig duties, including drivetrain and joint development checks.
