Miniature Button Load Cell


Applied Measurements CDFM3 miniature button load cell is designed for compression measurement applications where there is little space available for transducer mounting.

With capacities from 0-100N up to 0-20kN available in a load cell measuring just 30mm in diameter and 12mm in overall height, the CDFM3 is the second smallest button load cell that we offer.  If you need load cell that is smaller still, the CDF miniature button load cell is available in capacities from 0-500N up to 0-2000N and measures 15mm diameter and 8mm in height.

The CDFM3 miniature 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.
