Title:
TEMPERATURE MEASURING METHOD FOR METAL
Document Type and Number:
Japanese Patent JPS5717825
Kind Code:
A
Abstract:
PURPOSE: To measure metal temperature without contact by measuring the metal temperature to be measured utilizing the variation of impedance caused said metal by interlinkaging said metal in the magnetic field of a solenoid coil.
CONSTITUTION: Magnetic flux of a coil 2 is interlinkaged with the aluminum pipe 3 and resistance variation of aluminum pipe 3, seen from a solenoid coil 2, is measured by an impedance bridge 5. Then, temperature of aluminum pipe 3 is measured.
