CALORIMETRE Russian patent published in 2010 - IPC G01K17/16 

FIELD: measurement equipment.

SUBSTANCE: invention relates to heating engineering and may be used for measurement of the amount of heat such as during combustion of the substance being studied. Its essence consists in the calorimetre containing a measurement cell wherein a calorimetric bomb is inserted. The calorimetre contains an additional thermoregulator on the inner shell whereof a heater and a resistance thermometre are arranged connected with an additional amplifier including a bridging device providing for maintenance of the shell temperature at a level 5-7°C lower than the thermoregulator temperature. Between the shells an air gap is provided for passage of heated air to the fan which is sucked from the ambient environment through the holes arranged in a circle in the upper part of the outer shell with a heat insulation gasket on the outer shell inner surface. The heat flow amplifier is positioned inside the cavity of the calorimetre cover heat insulator and is connected with the measurement and reference resistance thermometres with short conductors.

EFFECT: improved accuracy of measurement within a wide range of ambient temperatures and rapid development of the calorimetre operational temperature.
