1. A syringe pump, comprising:
a pressure sensor assembly configured to sense a force, the pressure sensor assembly comprising:
a plunger having a sensing surface configured to receive the force;
a first pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface; and
a second pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface; and
a processor coupled to the first and second pressure sensors, wherein the processor is configured to estimate a magnitude of the force.
