Axial force pressure transducer

Abstract:

A system and method configured to measure applied force and pressure on a load cell. The system includes an axial force pressure transducer having a hollow cross section having at least two strain sensitive regions, and a plurality of strain sensors connected to the at least two strain sensitive regions, wherein applied force and pressure is calculated based on strain measurements using mathematical formulae. A method of calibration of the axial force pressure transducer uses known applied force and pressure measurements to calculate a calibration matrix reflecting the strain sensitivities of the at least two strain sensitive regions.
