Abstract
Abstract A load cell with resistance strain gauges comprising a solid insertion piece placed between an internal projection of the cell housing and a resilient element, the thickness of said insertion piece being selected depending upon the thickness of the resilient element so as to make a constant value with it. The latter fact provides a means for maintaining the mounting size of the cell constant when loads being measured are changed within a wide range.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A load cell with resistance strain gauges comprising a housing, a resilient element responsive to a load being measured, said resilient element being accomodated within said housing and resting upon an internal projection of said housing, props of said resilient element, resistance strain gauges mounted on said props, an insertion piece placed between said internal projection of said housing and said resilient element, the thickness of said insertion piece being selected depending upon the thickness of the resilient element whereby the sum of said thicknesses has a constant value.
Claim 2
Dependent Claim
89 words
A load cell with resistance strain gauges comprising a housing, a resilient element responsive to a load being measured, said resilient element being accomodated within said housing and resting upon an internal projection of said housing, props of said resilient element, resistance strain gauges mounted on said props, an insertion piece placed between said internal projection of said housing and said resilient element, the thickness of said insertion piece being selected depending upon the thickness of the resilient element whereby the sum of said thicknesses has a constant value.
Claim 3
Dependent Claim
29 words
An apparatus as claimed in claim 1, in which said insertion piece is made of a material whose hardness is not less than 40 HRC, as of tempered steel.
Claim 4
Dependent Claim
40 words
An apparatus as claimed in claim 1, in which said props of the resilient element, intended for mounting said resistance strain gauges, are provided with axially extending grooves allowing said resistance strain gauges to be axially adjusted along said props.
