Abstract:
Pressure measurement device comprising:an elastic measurement element (12, 78), acted upon by a pressure to be measured; a measurement element housing (2), in which the measurement element is supported; a magnet (18) attached to the element and which is moved by the measurement element in reaction to a change of the pressure acting upon the measurement element along a substantially rectilinear path of movement; a first Hall sensor (38) operatively positioned to the side of the magnet outside its path of movement; an electronic circuit electrically connected to said first Hall sensor for processing the output voltage of the first Hall sensor into a first output signal; a sensor carrier (22), which supports said first Hall sensor and is attached to the measurement element housing; and a second Hall sensor (40) supported on the sensor carrier (22), said second Hall sensor being operatively positioned to the side of said magnet (18) outside its path of movement, said electrical circuit processing the sensor output voltage of the second Hall sensor into a second output signal.
