Abstract

The pressure transmitter comprises a Bourdon tube (11) which is sensitive to pressure and which has one or more points which can move as a function of the pressure. An electrical conversion element delivers an electrical signal which images the displacements of the mobile point(s) of the Bourdon tube. The electrical conversion element has a magnetic vane (15) attached by a coupling rod (14) to the free end (13) of the Bourdon tube (11) and thus mounted in a mobile fashion with respect to a magnetic circuit (16) which has three arms, each lateral arm (17) carrying a coil (18).
