How to measure the temperature of induction heating furnace?

The temperature of induction heating furnace is generally measured by measuring instruments. There is no good technical method. Generally, it is estimated based on experience without measurement.

1. Optical pyrometer, manual measurement, non-contact

2. Optical fiber measurement, non-contact type, is an automatic measurement, the meter displays the temperature of the part where the light is transmitted.

3. Thermocouple measurement, contact test, measure the temperature of the induction heating body.

Basically these three methods
