Temperature dropping
Some measurements have been done to establish the dropping temperature steps between different
control points :
¾
Ambient room temperature (burning room with controlled pulsed air)
¾
Front Face of the Camera
¾
Internal Temperature sensor (measure available with DemoGev).

Mainboard
It has been established that the steps are the following (after a certain time) :
¾
Ambient room to Front Face about :
+ 10°C
¾
Front Face to internal sensor about :
+ 15°C
Then an average of
+ 25°C
between the room ambient temperature and the internal sensor.
The specification limits have been fixed at :
¾
45°C for the ambient temperature
¾
55°C for the Front Face
¾
70°C internal Sensor.
The ambient temperature is necessary defined here as a pulsed air or with an air flow around the
camera otherwise the temperature around the Camera is not homogeneous and can be much more
important than the one measured in the room.
