Goldeye G/CL Technical Manual V4.2.0
Because the temperature difference achievable is 60 kelvin, the TEC can reach the
default setpoint at -20 degrees Celsius.
Thus, the G-032 Cool TEC2 will switch to the default setpoint at -20 degrees Celsius
and keep the sensor at that temperature.
Goldeye G-008 and CL-008 TEC1 example
This example explains the heat functionality of the single-stage TEC1.
The Goldeye G-008 and CL-008 TEC1 has four temperature setpoints:
•
+20 degrees Celsius,
•
+25 degrees Celsius (default),
•
+35 degrees Celsius, and
•
+50 degrees Celsius.
With cooling, it can achieve a maximum temperature difference of 20 kelvin
between housing and sensor.
For this example, it is assumed that the camera is started at an ambient
temperature of -5 degrees Celsius. The camera is supposed to work at a sensor
temperature of +35 degrees Celsius. It is likely that through internal heat-up alone,
the camera cannot reach the setpoint at +35 degrees Celsius.
•
If the
TemperatureControlTarget
of the camera
is not
activated, the camera
levels the sensor temperature at the low setpoint of +20 degrees Celsius.
