Strain sensing device with magnetic mounting
First Claim
1. A device for sensing deformation on a metal force carrying member comprising a strain sensing element, means operatively mounting said strain sensing element on said force carrying member, said mounting means including magnetic element means which permit said device to be secured on said force carrying member by means of magnetic attraction forces between said magnetic element means and said force carrying member as an incident to positioning of said mounting means on said member, and said magnetic element means having sufficient magnetic strength for enabling strain in said force carrying member to be transmitted through said mounting means to said strain sensing element while permitting selected manual removal and repositioning of said device on said force carrying member.

Abstract
A magnetically mountable device for sensing deformation from loadings on machine members. The device includes a strain sensing transducer, brackets between which the transducer is supported, and magnetic bracket mounts which permit the transducer to be easily mounted on the machine member by virtue of magnetic attraction forces between the mounts and the force carrying member and yet be readily repositionable on the member so as to facilitate location of points of maximum stress concentrations during a working cycle of the machine.
