FORCE STRAIN-GAUGE TRANSDUCER Russian patent published in 2000 - IPC

FIELD: measurement technology. SUBSTANCE: invention is designed to measure force applied to polished rod of machine-rocker of well sucker-rod pumped employed in oil production. The transducer incorporates two resilient members rigidly joined by means of strap with formation of U-shaped structure. Loading and supporting force-taking platforms of each member are developed through 180 deg one relative to another and form two three-point loading circuits ensuring self-setting of transducer. Resistance strain gauges put on resilient members are assembled in strain measuring bridge. Resilient members and strap can be made from U-shaped rolled products. EFFECT: simplified design and enhanced measurement accuracy. 1 cl, 2 dwg
