Overview
The MK909 is an industrial torque sensor that captures the torque of rotating or stationary mechanical parts in real time and converts it into a high-accuracy electrical signal, supporting automated control, energy optimisation and early fault warning.
Key Features
- Converts mechanical torque into a precise signal
- Supports automation and energy optimisation
- Enables early fault warning and load monitoring
- High accuracy (–) for precise measurement
- Aluminum alloy elastic element for durability and corrosion resistance
- Sealed to – for reliable operation in harsh environments
Applications
Applied to EV motor and gearbox test benches, industrial robot joints and tightening equipment, wind-turbine main shafts and gearboxes, mining machinery, ship drive shafts and CNC spindles.
