Typical applications:

Industrial production process

Paper and Printing Industry:

Scenario: Installed in drying equipment for paper, film, and fabric.

Application: Measure the combined heat flux of radiation and convection applied by infrared, hot air and other drying units on the surface of materials, accurately control the drying process, prevent excessive or uneven drying, and save energy.

In the field of architecture and energy conservation

Thermal comfort assessment: The human body's thermal sensation is not only affected by air temperature, but also significantly affected by radiant heat from windows, cold walls, radiators, and other sources. Sensors are used to measure "radiation temperature asymmetry" and evaluate whether there are uncomfortable conditions such as "cold radiation" or "hot radiation".

Floor heating/radiant panel system monitoring: measures the actual radiant heat flux emitted by floor heating or ceiling radiant cooling/heating systems for system control and energy efficiency management.

Meteorology and Solar Energy Utilization

Net radiation measurement: Two back-to-back sensors (one facing up and one facing down) are used to measure the balance between solar shortwave radiation and ground longwave radiation, known as net radiation. This is the core parameter for studying the energy balance on the Earth's surface and climate change models.

Solar radiometer: a sensor specifically used to measure total solar radiation (direct+scattered radiation), which is a key equipment for solar energy resource assessment, photovoltaic power plant site selection, and efficiency monitoring.

Application of fire engineering

Scenario: Installed on the top or wall of cable tunnels, computer rooms, warehouses, and clean energy power stations (such as lithium battery compartments and energy storage stations).

Application: As a heat flux meter, used for early fire detection. Before the appearance of an open flame, potential overheating faults or smoldering can generate abnormal thermal radiation. Heat flow sensors respond earlier and more sensitively than traditional temperature detectors, providing valuable time for early warning and fire extinguishing.

Aerospace field

Spacecraft thermal control system testing: In the thermal vacuum chamber that simulates the space environment on the ground, it is pasted on the surface of spacecraft models such as satellites and probes to calibrate and verify the thermal mathematical model of the spacecraft, ensuring that its thermal control design can work normally in the real space environment.

Clothing and equipment testing: Place it on the surface of a dummy's skin or on the outer layer of special clothing to quantitatively measure the thermal shock (heat flux density) that the human body model can withstand in simulating harsh environments such as extreme cold and high temperature, in order to evaluate the thermal insulation performance level of professional clothing.
