A multi-condition sensor, comprising a housing defining a component cavity, a pressure input tube disposed through the housing, a fault actuator disposed within the component cavity of the housing and in pressure communication with the pressure input tube through the housing, wherein the fault actuator is configured to extend and contract as a function of pressure from the pressure input tube, an alarm actuator disposed within the component cavity of the housing opposite the fault actuator and configured to be actuated by the fault actuator and to extend to a maximum fault position, and an adjustable alarm contact disposed on an opposite side of the alarm actuator within the component cavity and configured to be adjusted to a predetermined extension length from the housing to provide a predetermined alarm contact position.

A method of determining fluid pressure inside a conduit. The method includes positioning a conduit in a surgical system. The conduit having an external surface, and the surgical system having a pair of sensors. The conduit is positioned in the surgical system such that the external surface of the conduit applies a force on the pair of sensors when the conduit expands. The method includes a step of generating one or more electrical signals with the pair of sensors. The one or more electrical signals corresponding to the force on the pair of sensors. The method includes a step of determining the fluid pressure inside the conduit by converting the one or more electrical signals into a fluid pressure value through a controller.
