Abstract

A pressure gauge comprising a stem having an inlet at which pressure is sensed. A Bourdon tube is coupled to the stem and is displaceable in response to pressure changes at the inlet. A movement comprising a movement plate conducts displacement of the Bourdon tube to a pointer shaft. A circuit board comprising an inductor is fixed relative to the stem. The movement plate comprises an integral flag connecting the movement to the Bourdon tube and an integral inductive target operatively positioned relative to the inductor.
