3 Overview
Radiometer is mainly used in public places and labor hygiene, heating and ventilation, building energy and other areas of radiant heat
measuring. Radiometer is usually composed of radiation probe, signal processing unit and reading display unit, shown in Figure 1,
Wherein the radiation probe is composed of an alternating absorption layer and a reflective layer, a sensor, a heat sink substrate and the like.
Figure 1 Schematic diagram of a radiant heat meter
Radiation heaters work is the principle of radiation in the radiation, the radiation absorption layer of radiation absorption heat after the temperature rise
High, so that the sensor produces an electrical response. Absorption layer spectral response flat, almost absorb all the radiant heat; and reflective layer
Almost no absorption of any radiant heat, the sensor generated by the electromotive force is almost zero. The absorbent layer is produced with a sensor for the reflective layer
The electrical response can be compared with the heat sink base can eliminate the background temperature changes generated by the impact of electrical response, the radiation heat
The generated electrical response is processed by the signal processing unit and the reading is displayed by the reading display unit, and the unit of measurement
Often W/m2 or kW/m2.
4 Measurement performance requirements
4.1 Zero drift
When the radiometric value of the radiometer is zero, the maximum drift of the zero point within 5 minutes does not exceed ± 1% of full scale.
4.2 The relative value of the irradiance error
Radiometer heat irradiance relative to the indication error of not more than ± 10%.
