Abstract

PURPOSE: To make it possible to detect the temperature in a wireless manner, while dispensing with a battery, by providing a resonance circuit including a detecting element of a temperature sensitive unit and an antenna.
CONSTITUTION: A metal pipe 2 to be inserted into a material in an electronic range to be heated is equipped at its one end with a temperatuer detecting element 1, which has its resonance frequency varied with the variation in temperatuer, and at its other end with a transmitting and receiving antenna 7. The pipe 2 is further equipped at its center portion with a capacitor 8 of variable type. Thus, the element 1, the antenna 7 and the capacitor 8 constitute together a resonance ciruit. On the other hand, the pipe 2 is formed at its preset position with a hole 13 which can adjust the capacity of the capacitor 8. As a result, the temperature of a material to be heated can be known by receiving the frequency of the resonance circuit.
