PRESSURE MEASURING SENSOR-RELAY Russian patent published in 2009 - IPC G01L19/12 

FIELD: physics, measurement.

SUBSTANCE: invention relates to instrument engineering, in particular to devices converting movement of sensing elements caused by gas or fluid impact into electric signals. Pressure measuring sensor-relay comprises an electronic unit and a measuring unit made as upper and lower bases with a feeding connector in which a sensing element with rigid centre in the form of metal convoluted diaphragm is fixed. Loose plates with concentric bulges and dimples identical to the diaphragm riffles are set between the upper base and the diaphragm and between the lower base and the diaphragm.

EFFECT: expanding functionality of units for controlling pressure and rarefaction of automated manufacturing procedures.
