1. A pressure sensor system comprising:

  • a sensor for measuring the pressure inside a structure;

    a movable plunger disposed in communication with the structure and the sensor, wherein the movable plunger applies a force against the sensor and is oriented so that, the magnitude of the force applied to the sensor by the movable plunger changes relative to a change in pressure inside the structure; and

    a biasing mechanism which biases the sensor toward the plunger;

    wherein the structure comprises tubing of an infusion set;

    wherein the sensor is disposed on a pump having a pump mechanism, and wherein the tubing is positioned adjacent the sensor and the pump such that the tubing is in communication with the movable plunger and the pump mechanism.
