Abstract

PURPOSE: To enhance the measuring accuracy with the use of a simple construction by using measuring and standard detectors and resonant circuits, which have their electric and temperature characteristics made equal, so that they may coact to hold an equal temperature.
CONSTITUTION: When the transmission characteristics of a measuring detector DET 1 are varied with the temperature variation, the transmission characteristics of a standard detector DET 2 which is made to have the same transmission characteristics and which is made thermally coactive therewith are varied at the same rate. In case the equivalent series resistor of an inductor L1 of a measuring resonant circuit is varied with the temperature variation, the equivalent series resistor of an inductor L2 of a standard resonant circuit is varied at the same rate. As a result, the measuring output of the rate of the two detecting output voltages, i.e., the indicated value of a meter M is held constant. In case the output voltage of the oscillator 1 is varied, the varying ratio of the resonant voltages of the two resonant circuits becomes equal to offset the influences upon the indicated value of the meter M.
