1. A pressure transducer comprising:

  • a first sensor; and

    a second sensor;

    the first and second sensors having substantially similar error characteristics, each of the first and second sensors being arranged to be subjected to at least one of a first pressure and a second pressure and to provide an output indicative of the pressure exerted thereon, the outputs of the sensors being electrically cross-coupled to each other so that an error in the first sensor is compensated with a substantially similar error in the second sensor.
