ABSTRACT:
A manometer device for continuous monitoring of the air pressure in vehicle tires is described which consists of a manometric capsule and an electrical indicator device associated therewith. A flatly conical membrane with a cylindrical projection is arranged transversely through the interior space of the manometric capsule. A permanent magnet is inserted in this projection. The membrane divides the interior space of the manometric capsule into two chambers, of which one chamber is stressed with a nominal pressure and the other chamber is connected to the pressure space of a vehicle tire. A stationary sensor, which is associated with the manometric capsule to be mounted on a rim flange, responds to linear magnetic field variations and transmits the latter to a terminal.
