Problems solved by technology

The temperature measurement process is that the measured object transmits the temperature to the thermistor, the characteristics of the thermistor change, and the electrical signal of the thermistor is judged to detect the temperature. There is heat loss during the heat transfer process, and there is a certain hysteresis , so that the temperature measurement is not accurate enough

Abstract

The invention relates to an inductive temperature measuring device which is characterized in that the inductive temperature measuring device comprises an electromagnetic device capable of generating an electromagnetic signal and a control unit which is connected to the electromagnetic device and can detect electrical parameters in the electromagnetic device. The electromagnetic device comprises amagnetic core and an electromagnetic coil, the magnetic core includes a magnetic core middle pillar, the electromagnetic coil is arranged at the periphery of the magnetic core, the electromagnetic device can generate an electromagnetic signal after being energized, and the inductive temperature measuring device further comprises a temperature sensing layer capable of sensing the electromagnetic signal generated by the electromagnetic device. According to the inductive temperature measuring device, a traditional temperature measuring method is changed, the temperature of a temperature sensing layer is detected by the action of the electromagnetic signal, according to the detection method of the invention, the heat transfer between a tested object and the electromagnetic device is not needed, the temperature of the tested object can be directly tested without the loss of heat and without a heat transfer process, and the temperature measurement is more timely and more accurate.

Description

technical field [0001] The invention relates to an induction temperature measuring device and a temperature measuring method, and at the same time, the invention also relates to a cooking device and an electromagnetic device. Background technique [0002] Existing temperature measurement technology usually uses thermistors, which are a type of sensitive components. According to different temperature coefficients, they are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC). . A typical feature of a thermistor is that it is sensitive to temperature and exhibits different resistance values ​​at different temperatures. A positive temperature coefficient thermistor (PTC) has a larger resistance value at higher temperatures, and a negative temperature coefficient thermistor (NTC) has a lower resistance value at higher temperatures. The temperature measurement process is that the measured object transmits the tem...
