Abstract

PURPOSE:To produce elements which can perform accurate measurement in large quantity by dividing at least one of resistors in a bridge circuit into two parts, arranging the resistors at the maximum elongated strain region and contracted strain region, providing variable compensating resistors at the location other than the strain region and connecting them. CONSTITUTION:An insulating film 10, a thin resistor film 11' and a thin connecting film 12' are formed on a strain generating part 5 of a beam body 1. Then etching is performed. A connecting line 12 remains intact as shown in the Figure. The thin connecting flow film 12' on the parts of resistors 11A1-11D2 and compensating resistors 13A-13B is removed. The thin films 11' and 12' on the other parts are removed. The bridge circuit wherein the resistors 11B1-11B2 are arranged with the divided resistors 11A1 and 11A2 is formed. A voltage is applied to one of two pairs of lead wires 16, and an output meter is connected to detect the strain to the other. The variable compensating resistos 13A and 13B are connected between the resistors 11A1 and 11A2 and between 11C1 and 11C2. In this constitution, the connecting wire 12 does not crosss and does not pass the strain region, accurate adjustment of balance can be performed by the compensating resistors, and the elements, which can perform highly accurate measurement can be produced in large quantity.
