THERMOELECTRIC HEATING, COOLING AND ENERGY GENERATION FOR SYSTEMS WITH REMOTE DIAPHRAGM WITH DIRECT INSTALLATION AND DUAL COMPARTMENT FOR FILLING LIQUID Russian patent published in 2019 - IPC G01L19/06 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment and can be used for measuring industrial process pressure in medium of high or low temperature using a transmitter. Essence: unit (702) of pressure transmitter for measurement of pressure in industrial process includes pressure sensor (500) made with possibility to perceive pressure of process. Connecting coupling (606) connects pressure sensor with industrial process by means of elongated housing (610) with capillary tube (602) with filling fluid medium. In the elongated body there is at least one thermoelectric element (620) located nearby the capillary tube for supply of heat to the coupling or removal of heat from it in response to the supplied electric signal.

EFFECT: this allows to heat the filling fluid medium to facilitate cold start or calibration and to cool the coupling during high-temperature operation.
