The CMP10 Pyranometer is a Spectrally Flat Class A pyranometer which provides a faster response, better linearity and a wider measurement range than the CMP3 and CMP6. The CMP10 uses a 32-junction thermopile detectors and provides an expected output of 0-21mV based on a sensitivity of 7 to 14µV/W/m². The CMP10 has two, 2mm thick, high quality concentric domes which reduces directional error and improves thermal isolation. The CMP10 also has built-in temperature compensation and an internal desiccant that lasts for 10 years. Spectral range of 285 to 2800nm. The sealed construction and 10 year desiccant pack makes this pyranometer ideal for long-term installations for meteorological, hydrological and agricultural applications in difficult to reach locations.
The housing design of the CMP10 provides a large capacity internal drying cartridge that can last for up to 10 years. The only maintenance that is required is to periodically clean the dome of the pyranometer, which can be maximised by fitting the CVF4 ventilation unit to your CMP10. The CMP10 also features a passive temperature compensation circuit with a standardised linear function.
The CMP10 has a 32-junction thermopile sensing element which features faster response, better linearity and a wider measurement range than the CMP3 and CMP6. The maximum operational irradiance level increase to 4000W/m²
The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The connector is a water proof socket fitted with the signature yellow signal cable and has gold-plated contacts allows for easy exchange and re-calibration. The signal cable is available in 10, 25 and 50m lengths.

The CMP 10 pyranometer is provided with two holes for 5mm screws. Two each of stainless steel screws, washers and nuts are provided in the fixing kit, and two nylon insulation rings. The pyranometer should first be secured lightly with the screws to a solid and stable mounting stand or platform. The nylon insulators are important to prevent corrosion between the stainless steel screws and the aluminium pyranometer housing.
CMF 1 and CMF 4 mounting fixtures for unventilated or ventilated (respectively) CMP series pyranometers and can also be used with the CMB 1 mounting bracket for pole or wall mounting.
An Adjustable Tilt CMP Mounting Kit is available to allow the CMP 10 to be mounted at any angle from 0° to 90° to provide an accurate reading for the position and angle of fixed photovoltaic panels. The position and angle of solar panels make a big difference to the performance and return on investment of a solar energy power plant. A horizontally mounted pyranometer measures the global short-wave radiation from the sun and sky in a way that is easily comparable with other sites and with solar energy database information. However, for fixed angle (non-tracking) PV panels it is important to know the energy available within the ‘view’ of the panel. The kit can be fixed to a horizontal surface and has a clear scale in degrees, and a secure locking device, for easy adjustment of the angle of a pyranometer from horizontal to vertical. It can also be fitted to the CMF 4 mounting fixture for simple attachment to walls and poles using the CMB 1 mounting bracket.
The CMP 10 pyranometer features a snap-on white sun shield, integrated leveling and a weatherproof connector which can be supplied pre-wired with 10m, 25m, 50m or 100m of signal cable for simple installation.
To improve the measurement accuracy of the CMP Series pyranometers the CVF4 ventilation unit can be used. It can be used outdoors under all weather conditions and includes a built in heater to keep the air just above ambient temperature which helps disperse precipitation and melt frost, or even melt snow and ice in cold climates. The CVF4 has a tacho output that can be used to check the proper operation of the CVF4. The output signal is 5V and nominal output should be at 146Hz. Higher frequency would suggest the filter needs replaced, whilst lower frequency could highlight an issue with the ventilator.
