MS-202 Pyrgeometer
- 3µm - 50µm flat spectral reponse
- Low window heating
- Dome temperature sensor
- Temperature compensation
Pyrgeometer MS-202 is designed to measure long-wave radiation above 3µm. A coated Silicon dome transmits incident radiation which above 3µm by cutting off the shorter wavelengths of the Sun spectrum. An electronic compensation circuit with a thermistor is integrated into the MS-202. This circuit is used for the sensor body temperature measurement or to measure long-wave downward radiation in the active mode. The analog output voltage of the detector is linear to the net radiation emitted by the atmosphere and ground. A thermistor dome temperature sensor is available as an option. Pt-100 temperature sensor for both the sensor body temperature and the dome temperature is also available as an option.
