Overview
The MK1203 is a bearing-block type weighing sensor designed to measure force and load through a machine’s bearing support, enabling integrated weighing directly at the shaft mounting. Its compact, built-in form suits continuous load monitoring within rotating support structures.
Key Features
- High accuracy (0.03~0.05%F.S) for precise measurement
- Alloy steel elastic element for durability and corrosion resistance
- Sealed to – for reliable operation in harsh environments
- Standard output 2.0±0.01mV/V, compatible with common indicators
- Compact design for straightforward integration
Applications
Applied in industrial automation, aerospace, and automotive engineering where integrated load and weight measurement is required.
