ABSTRACT:
A load sensor is made of a load-sensitive element made preferably of an aluminum alloy, a bridge circuit with strain gauges made preferably of tantalum nitride and formed on the load-sensitive element, and two operational amplifiers with their non-inversion input terminals connected respectively to the signal output terminals of the bridge circuit and their inversion input terminals connected to each other through a temperature-sensitive resistor having a positive second-order temperature coefficient and a precision resistor. The resistance values of these resistors are adjusted so as to compensate for the first-order and second-order temperature coefficients of the temperature-dependent output from the bridge circuit.
