Radiation Sensor Cm3P; Installation - Priva Compass Installation Manual

Radiation sensor CM3P

Radiation sensor CM3P
The Radiation sensor (also called a pyranometer) measures a part of the spectrum of sunlight,
including the infrared part. The Radiation sensor therefore measures the quantity of incoming
radiation energy that the sun introduces into the greenhouse. You can use this sensor for energy
calculations.
The Radiation sensor CM3P consists of a black body with thermopile, the output signal of which is
dependent on the quantity of radiation collected.
The Radiation sensor CM3P is supplied with a calibration certificate. If the calibration
certificate is missing, you can also find the data on a sticker on the sensor. To do this, remove
the sensor from the black housing.

Installation

1. Remove the two socket head screws (including clamping rings) on the underside of the Radiation
sensor CM3P.
2. Guide the cable through the appropriate opening on the Meteorological station.
The Radiation sensor CM3P has a set position on the Meteorological station. See
sensors on the supports of the Meteorological station (page
• Mount the Radiation sensor CM3P in such a way that the arrow on the housing is
pointing in the direction of the nearest pole.
• Avoid cast shadows at locations between 15° N and 15° S (near the Equator) mount
the sensor on a separate mast, on the upper support.
3. Mount the Radiation sensor CM3P with the two socket head screws (including washers) on the
support of the Meteorological station.
4. Feed the cable through the hole in the clamp block assembly so that the cable re-emerges on
the underside of the block.
