Abstract
A pressure sensor includes an evaluation unit and a sensor assembly, which includes a sensor and an electrode arrangement. The sensor generates signals under the action of a pressure profile, and the electrode arrangement transmits the signals to the evaluation unit, which includes an evaluation unit housing, an electric circuit board and a reinforcement element, which is arranged in a radial plane between the electric circuit board and the evaluation unit housing. The reinforcement element is mechanically connected to the electric circuit board and dampens mechanical resonance vibrations of the electric circuit board that occur in the radial plane.
Claims19
A pressure sensor comprising:
- a sensor assembly that includes an electrode arrangement and a sensor;
- which generates signals under the action of a pressure profile;
- an evaluation unit that is electrically connected to the electrode arrangement to receive the signals transmitted from the electrode arrangement;
- and wherein:
- the evaluation unit includes an evaluation unit housing, an electric circuit board and a reinforcement element, which is arranged in a radial plane between the electric circuit board and the evaluation unit housing and defines a hollow cylinder that elongates along a longitudinal axis for the entire length of the electric circuit board and is configured to hold the electric circuit board immobile relative to the evaluation unit housing;
- and the reinforcement element is mechanically connected directly to the electric circuit board so as to dampen mechanical resonance vibrations of the electric circuit board that occur in the radial plane.
