FIELD: measurement equipment.
SUBSTANCE: pressure metre, comprising at least one pressure hall effect sensor (11), at least one associated magnet (6), movable relative to it in accordance with the pressure subject to measurement, and at least one protective screen (13), made of a ferromagnetic material, which surrounds the sensor (11) and the magnet (6), at the same time a screen (13) has one side (13') closest to the sensor (11), in which a deepened section (17) is formed, in direction of the sensor (11), to amplify a magnetic flow. At the same time the pressure metre additionally comprises a body (102) of a base equipped with an input (100) for fluid medium and a chamber (110), which communicates with the input (100), a membrane (2), which supports the magnet (6), which tightly seals the chamber (110), and a cap (7), arranged around the specified membrane (2) to support the specified screen (13).
EFFECT: improvement of noise immune properties of a sensor.
