4.7.2 TEMPERATURE MEASUREMENT/REGULATING CIRCUIT – INCUBATION
MODE
Short description:
Sample chamber with controlled, directly mounted heating lines. The unit's air
jacket supports the temperature equilibrium.
Exterior door with mounted heating lines to prevent condensation from forming
on the glass.
μP-based temperature regulator with PT1000 as the temperature sensor
(integrated in the sensor block).
μP-based sample protection function with an upper limit band value that serves
as the trigger threshold to activate the software module.
Plausibility check of the temperature sensor signals (PT1000 and digital sensor,
LM 75, in the sensor block).
The individual heating circuits are activated separately, and for varying lengths
of time.
