Abstract
PURPOSE:To reduce power consumption at a load cell part, by connecting those located diagonally one to another in series among strain gauges stuck at a strain sensing section of a double beam type straining body to form a half bridge circuit. CONSTITUTION:Four strain gauges T1, T2, C1 and C2 are stuck on a straining body Y. Then, the strain gauges on the extending side of a strain sensing section of the straining body Y are connected in series to those located on the reducing side thereof, diagonally with respect to the former. In other words, the strain gauges T1 and T2 and C1 and C2 are connected in series to each other respectively to form a half bridge circuit and an output signal is taken at a connection point between both the series connection circuits. In this case, when T1=T2= C1=C2=R, the total resistance (r) of the half bridge circuit amounts to 4R to provide a resistance four times as large as a combined resistance of the conventional full bridge. This can enhance the action of limiting current thereby enabling a reduction in the power consumption.
