Pyrgeometer with heater and 4-20 mA transmitter

IR02-TR is a pyrgeometer suitable for longwave irradiance measurement in meteorological applications. The instrument can be heated, which improves measurement accuracy by mitigating dew and frost deposition on its window. IR02 houses a 4-20 mA transmitter for easy read-out by commonly used data loggers. IR02-TR measures the longwave or far-infrared radiation (FIR) received by a plane surface, in W/m2, from a field of view angle of approximately 150 °. Longwave radiation is the portion of atmospheric radiation that is not emitted by the sun. While the actual field of view angle is not the ideal...

Using IR02-TR is easy. It connects directly to commonly used data logging systems. The irradiance in W/m2 is calculated by using the transmitter's output and temperature reading. The final result is calculated by taking into account the irradiance radiated by the sensor itself (Stefan-Boltzmann law). In IR02-TR's standard configuration, the 4 to 20 mA output corresponds to a transmitted range of -300 to +100 W/m2, which can be adjusted at the factory upon request. - general meteorological observations - climatological networks - agricultural warning networks (frost) IR02-TR design IR02-TR employs...
