Description:

Long-wave radiation sensor/earth radiation sensor, based on the principle of thermoelectric effect, is used to measure infrared radiation with a wavelength range of 4 to 50μm from the atmosphere and the earth's surface. It consists of a silicon arc filter cover, a sensing element, a thermistor, a meter body, a shading plate, a desiccant window and other components. The sensing element consists of a wound electroplated multi-junction thermopile, and the sensing surface is coated with a high-absorption matte black coating to absorb radiation energy. The heat generated passes through the thermal resistor, causing the temperature of the thermopile to change and convert it into a voltage signal output. The sensor integrates a temperature compensation device.

Features:

Thermoelectric effect principle
Multi-node thermopile
Complies with CIMO Guide
Small heating effect of the silicon cover
Small cosine response error
No power supply required
Passive accurate measurement
