THERMOELECTRIC CONVERTER AND METHOD FOR METROLOGICAL CONTROL DURING OPERATION WITHOUT DISMANTLING FROM OBJECT Russian patent published in 2016 - IPC G01K15/00 G01K7/02 G01K13/12 

FIELD: measuring equipment.

SUBSTANCE: invention relates to thermometry and can be used for measuring temperature of an object. Thermoelectric converter comprises protective cover (1), thermometric insert, guide tube (2) for temporary placement of control means for temperature measurement and terminal block. Thermometric insert consists of two identical working thermocouples (3), arranged in symmetry axis of guide tube (2) with matching of their ends with end of protective cover (1). Cold ends of homogeneous thermoelectrodes working thermocouples (3) are electrically connected. In guide tube (2) there is a portable thermophysical model (4) of reference thermocouple. Disclosed method involves periodic arrangement of control means of measuring temperature in guide tube (2), comparison of its readings with readings thermometric insert and removal of control means of measuring temperature of guide tube (2). Measurement of temperature in guide tube (2) is performed with reference thermocouple. Thermophysical model (4) of reference thermocouple is extracted from guide tube (2) and reference thermocouple is placed therein until alignment of its end with end of protective cover (1). After said comparison procedure, reference thermocouple is removed from guide tube (2) and thermophysical model (4) of reference thermocouple is placed therein.

EFFECT: high accuracy of thermometry.
