Overview
The MK903 and MK903-T are torque sensors intended for static and non-continuous rotary torque measurement and control. They combine high accuracy and stable performance with convenient installation, converting applied mechanical torque into a precise signal so drive-train and assembly equipment can be verified and tuned.
Key Features
- For static and non-continuous rotation torque
- High accuracy with stable output
- Convenient, simple installation
- Real-time torque-to-signal conversion
- High accuracy (±0.1/0.2/0.3%F.S) for precise measurement
- High-quality alloy steel elastic element for durability and corrosion resistance
Applications
New-energy vehicle motor and transmission test benches, wind turbine load monitoring, robot joint and bolt-tightening equipment, and CNC machine spindle torque checks.
