Abstract : The temperature coefficient of modulus of elasticity of sensing element material result in temperature effect on rated output of strain gauge load cell. It is possible to reduce the effect since every sort of sensing ele2 ment material has a definite temperature coefficient of modulus. Experimental result show that the temperature effect could be improved greatly using the test and calculate compensation method , and could be reduced to 0. 01 %FS/ 10K.
Key words : strain gauge load cell ; temperature effect on rated output ; temperature compensation
