APPARATUS FOR STABILISING AIR TEMPERATURE OF ALTITUDE TEST CHAMBER Russian patent published in 2012 - IPC G05D23/30 G05D23/12 G01L23/04 

FIELD: physics.

SUBSTANCE: apparatus for stabilising temperature in an altitude test chamber has series-connected thermoelectric modules and heat exchanger radiators, digital-to-analogue converters with a current output, a temperature sensor and a pressure sensor. By using thermoelectric modules to stabilise air temperature in an altitude test chamber, the present invention enables to achieve high quality of installing and controlling temperature regulators since all mechanical elements of the temperature regulators are not exposed to temperature fluctuations.

EFFECT: stabilising temperature in an altitude test chamber when controlling temperature regulators to reduce additional error in operation of the temperature regulators and preventing forbidden deformation of the bellows of the temperature regulators.
