Temperature measurement
To control and regulate the internal camera temperature, three temperature
sensors are available within the camera. Use the
DeviceTemperatureSelector
feature to select a temperature sensor, as listed in
. The temperature of
the selected sensor is displayed with the
DeviceTemperature
feature.
Switching temperature setpoints
The Goldeye temperature control allows to switch between setpoints manually or
automatically.
If set to
Auto
, the TEC switches up or down to the next setpoint, based on the
temperature inside the camera. Note that the TEC does not switch up or down
immediately after the next setpoint is reached. The switch only takes place when
the temperature has exceeded the setpoint by a few degrees.
TECless models do not switch setpoints.
Switching to the higher setpoint
After powering up the camera, at first the camera temperature rises. This is due to
heat generation inside the camera, and possibly caused by warm ambient
temperature. To keep the sensor temperature constant, the TEC keeps it at a
predefined temperature setpoint (see
).
The TEC keeps the sensor temperature as long as the difference between sensor
temperature and case temperature does not exceed the predefined
Δ
T (see
).

(Default)
Temperature sensor beside the camera sensor.
Sensorboard
Temperature sensor on the sensor board.
Mainboard
Temperature sensor on the main board.

Only the sensor board is switched off
•
If the internal temperature exceeds the Alert limit, only the sensor and the
cooling is shut down.
•
The camera is not powered down.
•
You may bring back the camera to normal operation after it is
cooled down
sufficiently.
•
To do so, switch the power supply off and switch it on again.
