Abstract: A SAW based pressure sensor comprises a base (2a) having an aperture (3) formed therein and a substrate (4) mounted on the base so as to completely overlie the aperture. The substrate (4) is adhered to the base (2a) so as to form a fluid tight seal around the periphery of the aperture (3). A first SAW resonator (5) is mounted on the substrate (4) wholly within the region overlying the aperture (3), whilst two further SAW resonators (6, 7) are mounted on the substrate wholly within a region which is stiffened by adhesion to the underlying base (2a), such that the two further SAW resonators (6, 7) are completely decoupled from the strain field arising in the substrate due to deflections thereof.

Abstract: A method, system and device for providing device specific calibration data for a sensor. A sensor device includes a transmitter, receiver, memory and a response portion responsive to a selected condition of the region. Generic calibration data associated with a group of sensors into which the sensor device falls is then stored in a database remote from the sensor device. Correction data for use in modifying the generic calibration data to more accurately fit the actuation calibration data of the sensor device is stored in the memory portion of the sensor device. The sensor device is interrogated with an interrogator device to obtain the correction data, and the generic calibration data relating to the sensor device is retrieved from the database and modified using the correction data to produce sensor device specific calibration data.
