BLOCK, SENSITIVE TO PROCESS FLUID PRESSURE, FOR PRESSURE TRANSMITTERS UNDER HIGH WORKING PRESSURE Russian patent published in 2017 - IPC G01L19/06 

FIELD: machine engineering.

SUBSTANCE: transmitter contains: a body; pipe flange, attached to the body, designed to accommodate the transmitter in the pipe opening; a measuring device, running from the flange and into the pipe through the opening. The measuring device has a support (40) of the pressure transmitter, which has a support (36) therein. The pressure transmitter (52) runs through and is installed in the opening (36). The pressure transmitter (52) has an electrical characteristic, which changes under the applied pressure. The insulator insert (50) is designed to be effected by the process fluid. The insulator insert has an insulating diaphragm (64), positioned to contact with the process fluid. The channel (66) is connected through the fluid to the insulating diaphragm (64) to pass the process fluid pressure from the insulating diaphragm (64) to the transmitter (52) by means of incompressible fluid. The support (40) of the pressure transmitter is connected to the insulator insert (50) and has a noncircular shape if observed along the opening axis.

EFFECT: creation of a compact device sensitive to pressure, without physical contact of particles or solid substances in the process, having an insulating diaphragm.
