Sensor apparatus systems, devices and methods

A manifold interface for coupling a manifold of a disposable fluid handling unit for use in a fluid pumping system to a base control unit of the fluid pumping system, the manifold interface comprising:

• a housing comprising a coupling side that includes a sensor probe extending away from the housing and configured and arranged to mate with a corresponding sensor well on a coupling side of the manifold of the disposable fluid handling unit;
• the sensor probe configured and arranged to detect temperature or electrical conductivity of a liquid in a manifold channel into which the sensor well extends;
• the housing comprising a data key interface configured and arranged to interface with a corresponding data key on the manifold of the disposable fluid handling unit;
• wherein the data key interface is configured and arranged to provide a communication interface through which a controller of the base control unit can read information from the data key on the manifold of the disposable unit.
