Overview
The MK904-A is a strain-gauge torque sensor designed for static torque measurement. Both ends use key connections for simple, reliable mounting, and it delivers high accuracy, stable performance and a wide measurement range.
Key Features
- High accuracy (±0.1 / 0.2 / 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
Intended for measuring and controlling torque in static and non-continuous-rotation applications such as assembly and fastening.
