Description & Specifications
Solar Radiation Sensor
Technical Specification
The transducer is an hermetically-sealed silicon photodiode; the
included amplifier converts the transducer current into 0 to +2.5 VDC.
The Solar Radiation Sensor, or solar pyrometer, measures global
radiation, the sum at the point of measurement of both the direct and
diffuse components of solar radiance, the sensor's transducer, which
converts incident radiation to electrical current, is a silicon
photodiode with the wide spectral response.
It includes a cutoff ring for cosine response, a level indicator, and fins to aid in aligning the sensor with the sun's rays.
The space between the shield and the body also provides a runoff path
for water, greatly reducing the possibility of rain- or irrigation-water
entrapment.
It integrates the radiance values and displays total incident energy over a set period of time.
The outer shell shields the sensor body from thermal radiation and
provides an airflow path for convection cooling of the body, minimizing
heating of the sensor interior.
From the sensor's output voltage, the console calculates and displays solar radiance.
Spring-loaded mounting screws, in conjunction with the level indicator, enable rapid and accurate leveling of the sensor.
The diffuser is welded to the body for a weather-tight seal; it provides an excellent cosine response.
