Goldeye G/CL Technical Manual V4.1.1
Thus, the G-032 Cool TEC2 will switch to the default setpoint at -20 °C and keep the
sensor at that temperature.
Example for Goldeye G/CL-008 TEC1
This example explains the heat functionality of the single-stage TEC1.
The Goldeye G/CL-008 TEC1 has four temperature set20 °C,
+25 °C (Default), +35 °C, +50 °C. With cooling, it can achieve a maximum
temperature difference of 20 K between housing and sensor.
For this example, it is assumed that the camera is started at an ambient
temperature of -5 °C. The camera is supposed to work at a sensor temperature of
+35 °C. It is likely that through internal heat-up alone, the camera cannot reach the
setpoint at +35 °C.
With the G/CL-008 TEC1
•
If the
TemperatureControlTarget
of the camera
is not
activated, the camera
levels the sensor temperature at the low setpoint of +20 °C.
•
If the
TemperatureControlTarget
of the camera
is
activated, the camera
heats the sensor and levels the temperature at the setpoint of +35 °C.
