Description of functions
4.4 Sensor system in SUNTEST CPS+
SUNTEST CPS+ has integrated sensors:
•
Sensor for measuring the global irradiance (E) in the
range of 300 - 800 nm and for regulation in the range of
250 -765 W/m²,
• Sensor for measuring and regulating the black stan-
dard temperature (BST) up to about 100 °C,
• Sensor for measuring the test chamber temperature
(TCT).
Irradiance (E):
•
During testing, irradiance is measured by a photodiode
!
and regulated electronically to achieve a constant
value.
Black Standard Temperature (BST)
•
During testing the black standard sensor (BST sen-
sor)
"
continuously measures the temperature.
• The black standard temperature (BST) is regulated via
the speed of the test chamber ventilator.
Test chamber temperature (TCT):
•
The test chamber temperature (TCT) is measured by a
temperature sensor in the exhaust air flow of the test
chamber.
• The test chamber temperature cannot be controlled
and is indicated in the display unit of the program con-
troller.
Measurement data:
•
The measurement data can be transferred, with the
testing program running, via the RS 232-port at the
rear side of the unit
to a PC or a printer with a serial
interface.
