An apparatus for determining fluid pressure within flexible tubing has a magnet and a multidimensional magnetic sensor arranged to detect a magnetic field of the magnet along at least two dimensions. The magnetic sensor and the magnet are arranged such that a location of the magnet relative to the magnetic sensor varies as a function of the fluid pressure within the tubing, and a direction of a magnetic field vector at the magnetic sensor is dependent upon the location of the magnet relative to the magnetic sensor. The magnetic sensor detects at least two magnetic field strengths corresponding to strength of the magnetic field projected along each of the at least two dimensions, and generates an output signal related to the direction of the magnetic field vector at the magnetic sensor. The direction of the magnetic field vector is used as an indicator of the fluid pressure.
