Product information "Pyranometer CMP21"

The pyranometer is an instrument for measuring the solar irradiance. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square. The pyranometer is designed for continuous indoor and outdoor use.

The pyranometer features a snap-on white sun shield, integrated leveling and a weatherproof connector which is supplied pre-wired with 10 m of signal cable for simple installation. An optional mounting rod and longer cable lengths are available.

The Pyranometer does not require any power, it supplies a low voltage of 0-20mV in relation to the amount of incoming radiation. When a higher voltage level or a 4-20mA signal is required, the amplifier for pyranometer 469101 is the perfect solution.

For measuring of solar irradiance.
Consist of double precision glas dome, black thermopile, anodised aluminium case and sun shield.
The CMP 21 pyranometer is fitted as standard with a 10k thermistor temperature sensor, or optional Pt-100 and is supplied with individually measured temperature and directional response data.
