Overview
The MK908 is a compact, lightweight rotary torque sensor with high accuracy, good stability and strong immunity to interference. It captures torque changes on rotating or stationary machine elements and converts them into a precise electrical signal in real time, supplying the data behind automated control, energy optimisation and early fault warning.
Key Features
- High accuracy (0.2%F.S.) for precise measurement
- Aluminum alloy / Alloy steel elastic element for durability and corrosion resistance
- Sealed to IP64 for reliable operation in harsh environments
- Standard output 1.0~2.0mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Torque testing of electric motors, engines and rail traction; EV motor and gearbox benches; wind-turbine main shafts and gearboxes; robot joints and automated tightening tools; CNC spindles; mining and marine drives.
