DEVICE FOR AIR THERMOSTATTING OF CALORIMETRIC CELL Russian patent published in 2013 - IPC G01K17/08 G05D23/30 

FIELD: measurement equipment.

SUBSTANCE: device is proposed for air thermostatting of a calorimetric cell, comprising a cylindrical body, inside of which there is an isothermic shell. In the centre of the isothermic shell there is a calorimetric cell is fixed on special brackets, representing a cylindrical chromium-plated brass vessel with a tightly closing cover, in the centre of which there is a copper cylindrical sleeve fixed. The calorimetric vessel is tightly inserted into the sleeve for the tested solution, and the inner volume between the isothermic shell and the calorimetric cell is filled with a coolant - air. On the inner surface of the calorimetric cell there is a thermocouple temperature sensor. Electric connection of the calorimetric cell with metering circuits is carried out by wires laid inside brackets. The device is equipped with a double-circuit control system "heater" - "refrigerator", the base of the electric circuit of which is represented by a programmable double-channel PID controller TPM12, a heating circuit and a cooling circuit.

EFFECT: reduced duration to reach operating mode of a cell.
