Description
Applied Measurements CDF subminiature button load cell is designed for compression measurement applications where the absolute minimum of space is available for transducer mounting.
With capacities from 500N to 2000N available measuring just 15mm in diameter and 8mm in overall height, our CDF load cell is the smallest standard button load cell that we offer, however we can create smaller customised versions if required. If you need to measure lower or higher forces, the CDFM3 miniature button load cell is available in capacities from 0-100N right up 0-20kN and is slightly larger at 30mm diameter and 12mm in height.
The CDF subminiature button load cell is ideal for retro-fitment into industrial machines and process systems for monitoring and control purposes, or for incorporation into new machine designs.
