Title:
FINE VARIATION METER OF IMPEDANCE
Document Type and Number:
Japanese Patent JPS5430076
Kind Code:
A
Abstract:
PURPOSE: To compensate the temperature variation of a detecting coil to measure the fine variations such as temperature or external diameter by detecting the temperature of a detecting coil with the use of a temperature sensitive element and by converting the detected temperature into a voltage with the use of a converter so that the output may be used as means for compensating the meter body.
