PYRHELIOMETER

The CE 183 pyrheliometer can measure accurate direct radiation from 0.2 to 3µm. It can be used to compute Optical Thickness and Water Vapor quantity.

SPECIFICATIONS
Ultra stable thermopile
Sensibility 20 m/W/m-2
Field of view for rain : 3°
Spectral bandwidth : 200-4000 nm
Response time < 1s. for 1%
Linearity : 0.1°
Thermal compensation of the sense's sensitivity

Reference CE 183

Output
Version 183A
analogical lox-level (0-20 mV) output
100 W platinum probe at 0°C for correction
Version 183N
Numerical integration with automatic temperature
RS232 output for the integrated sequences (mn/mn) of direct radiation
Storage capacity : 1 week with a 1 mn stop

Enslave azimutal robot with digital integrator CE 315I
Sun follower : a motorized two axes robot
Movements angles : Azimuth 0-540° - Zenith 0-180°
Sun pointing is done by time equations, with a precision of 0.5°, the four quadrant tracker allows sun pointing with a precision of 0.1°

Applications
Precise direct radiation measurements from 0.2 to 3 mm
Optical thickness measurements
Water vapor quantity
Measurements in the bands UVA and UVB
