The CMP 3 pyranometer is used to measure 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 obtained is expressed in Watts per meter square (W/m²). The CMP 3 pyranometer is developed for continuous outdoor and indoor use. The CMP 3 pyranometer is designed for shortwave global solar radiation measurements in a spectral range from 300 to 2800nm.
Irradiance is measured by the thermopile detector up to 2000W/m² with a response time <18 seconds and typical sensitivity 10µV/W/m² that varies less than 5% from -10°C to +40°C.
The operating temperature range is -40°C to +80°C and the stability is higher than 1% per year.
The key features of the CMP 3 pyranometer are:
- A snap-on white sun shield, integrated leveling and a weatherproof connector which is supplied pre-wired with 10m of signal cable for simple installation.
- An optional mounting rod and longer cable lengths are available.
- Two CMP 3 pyranometers can easily be mounted back-to-back to make a low-cost albedometer.
- 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 AMPBOX is the perfect solution.
- Low cost radiometer for accurate routine measurements.
- Weatherproof cable connector.
- Easy way of leveling the instrument.
