APPARATUS FOR DETERMINING THE PARAMETERS OF EXOTHERMIC PROCESSES AT A PRESSURE ABOVE ATMOSPHERIC PRESSURE Russian patent published in 2021 - IPC G01N25/20 G01K17/06 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measuring equipment, namely to apparatuses for determining the thermal stability of liquid single-phase and two-phase systems, including heterogeneous ones. The claimed apparatus consists of an external temperature control unit (ETCU) with a cover divided into left and right parts, an internal forced heating and temperature control unit is placed inside the ETCU, located wherein is a reaction vessel with a cover provided with sealed inputs of chromel-alumel thermocouples intended for measuring the temperature at several points along the height of the reaction vessel, also located in the ETCU are a pressure sensor and a sealing unit of a safety membrane with an exhaust branch pipe, wherein the bodies of the external temperature control unit, the left and right parts of the cover thereof, the internal forced heating and temperature control unit constitute a heating element covered with a thermal insulation layer, the heating element is connected with the input-output of the control computer via a PID controller and an interface converter.

EFFECT: simplifying the design while maintaining the accuracy of measurements.
