Function description
4.4 Sensor system in SUNTEST XLS+
SUNTEST XLS+ has integrated sensors:
• Sensor for measuring and controlling the irradiance
(E) in the range 300 - 800nm,
• Sensor for measuring and regulating the black stan-
dard temperature (BST) in the range ambient tempe-
rature up to about 90°C,
• Sensor for measuring the test chamber temperature
(CHT).
Irradiance (E):
• During the testing, the irradiance is measured by a
photo-diode
!
and controlled electronically to achie-
ve a constant value.
Black Standard Temperature (BST)
• During the testing, temperature measurements are ta-
ken continuously by the black standard-sensor (BST)
".
• The black standard temperature (BST) is controlled
via the speed of the test chamber ventilator.
Test chamber temperature (CHT):
• The test chamber temperature (CHT) is measured by
a temperature sensor in the exhaust air flow of the
test chamber.
• The test chamber temperature cannot be controlled.
The test chamber temperature is indicated in the dis-
play unit of the program controller.
Measurement data:
• The measured data can be transferred, with the te-
sting program running, via the RS 232-port
#
to a PC
or a printer with a serial interface.
