CDFT Load Cell

Description

The CDFT micro button load cells are designed for the measurement of compressive forces where space is a limiting factor.  Its compact size means it can be fitted in the smallest of spaces and is often retrofitted into equipment to provide load monitoring.  It is suited for both force measurement and weighing applications alike.
