A syringe pump is disclosed that includes a pressure sensor assembly, a plunger, first and second pressure sensors, and a processor. The pressure sensor assembly senses a force and includes the plunger having a sensing surface configured to receive the force, the first pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface, and the second pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface. The processor is coupled to the first and second pressure sensors to estimate a magnitude of the force.
