It can be divided into contact heat flux sensor and non-contact heat flux sensor according to whether it is in contact

The contact heat flux sensor should be attached to or buried in the object to be measured when it is applied,such as building material heat flux measurement,pipe heat flux measurement, boiler heat flux measurement, skin heat flux measurement, etc. The choice of this type of heat flux sensor mainly depends on the application, determining the measurement temperature and the size of the sensor.

There is a certain distance between the non-contact heat flux ensor and the measured object, etc., to measure radiant heat flux and convective heat flux; this is generally divided into total heat flux sensor and radiant heat flux sensor.
