A plurality of pneumatic hydrostatic weight sensor (10.1, 10.2), each incorporating a fluid and a pressure sensor (20.1, 20.2) for sensing the pressure thereof, are incorporated in series with the load path within a vehicle seat (3) to sense occupant weight. A signal processor (50) measures the pressure within each pneumatic hydrostatic weight sensor (10.1, 10.2) and the weight of the occupant (5) from the signal (22.1, 22.2) generated by the associated pressure sensor (20.1, 20.2), and compensates for the effects of ambient pressure or temperature on the weight measurement responsive to the difference in pressure between the associated pressures of two of the pneumatic hydrostatic weight sensors (10.1, 10.2). |
