HIGH-TEMPERATURE PRESSURE SENSOR UNIT Russian patent published in 2009 - IPC G01L19/04 

FIELD: physics; measurement.

SUBSTANCE: present invention pertains to process sensors, used in systems for controlling and monitoring manufacturing processes. The invention particularly relates to sensors which measure process conditions in high-temperature media. The pressure sensor unit for measuring pressure of process fluids (104) comprises a unit (120) of insulating membrane. The pressure sensitive element (130) is put at a distance from the unit (120) of insulating membrane, so as to provide for heat insulation. Pipe (122) runs from unit (120) of insulating membrane to the pressure sensitive element (130) and is designed for carrying an insulating filling fluid. The support of the sensor joins the pressure sensitive element of the pressure sensor to the unit of insulating membrane so as to join the insulated cavity of the unit of insulating membrane and the pressure sensitive element.

EFFECT: increased accuracy of measurement and simplification of design.
