ABSTRACT:
A pressure sensor, which is to be used in an environment involving vibrations, includes a case and a sensor chip. The case has an inner surface that is to be disposed perpendicular to a direction of the vibrations. The sensor chip is to sense a pressure in the environment and generate a sensing signal representative of the sensed pressure. The sensor chip has a pressure-receiving surface and is secured in the case with the pressure-receiving surface perpendicular to the inner surface of the case. With such an arrangement, since the pressure-receiving surface of the sensor chip is accordingly to be parallel to the direction of the vibrations, the influence of the vibrations on the pressure-receiving surface can be minimized. Consequently, high accuracy of the pressure sensor can be ensured.
