Abstract
Provided is a constant voltage source for providing a reference constant voltage at a predetermined temperature, the temperature characteristics of an output of the constant voltage source being adjustable, and also provided is a bridge type measuring device comprising, a bridge circuit consisting of a plurality of detecting devices, at least one of resistance values thereof being varied in response to a variation in conditions of an object to be measured. An output compensating circuit for a bridge type measuring device can also be obtained by which the temperature characteristics of an output of the device may be adjusted utilizing the reference constant voltage of the constant voltage source which may be formed which comprises a memory storing a digital value and a digital-to-analog converter.
