PRESSURE SENSOR DEVICE |
摘要 |
A pressure sensor device comprises a casing (2a, 3 a) defining a chamber (20) and an inlet passage (14a, 14b) of the chamber. Accommodated in the chamber (20) is a pressure sensor (17) having a sensor body with a cavity and a membrane capable of deformation under pressure action of a fluid present in the inlet passage (14a, 14b). The device further comprises a circuit arrangement (26, 27, 30) to which the pressure sensor (17) is electrically connected, the circuit arrangement including a circuit support at least partially accommodated in the chamber (20). The sensor body is not rigidly associated to the casing (2a, 3 a) and/or to other parts of the device (26, 27, 30, 35), i.e. it is mounted elastically or in a moveable manner with respect to the casing (2a, 3 a) and/or to said other parts (26, 27, 30, 35) inside the chamber (20). |
