Overview
The MK904-B is a static torque sensor built on resistance strain-gauge measurement principles, offering high accuracy, dependable stability and a wide measurement range. Both shaft ends use key connections, making set-up and installation simple for torque measurement and control in static or non-continuous-rotation duty.
Key Features
- Strain-gauge principle, wide range
- Key connections at both ends
- For static and non-continuous rotation duty
- High accuracy (±0.1 / 0.3%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Standard output 1.0-1.5mV/V, compatible with common indicators
Applications
Suits assembly tightening checks, transmission-component test rigs and other applications measuring torque without continuous rotation.
