A sensor apparatus and sensor apparatus system for use in conjunction with a cassette, including a disposable or replaceable cassette. In some embodiments, the cassette includes a thermal well for permitting the sensing of various properties of a subject media. The thermal well includes a hollow housing of a thermally conductive material. In other embodiments, the cassette includes sensor leads for sensing of various properties of a subject media. The thermal well has an inner surface shaped so as to form a mating relationship with a sensing probe. The mating thermally couples the inner surface with a sensing probe. In some embodiments, the thermal well is located on a disposable portion and the sensing probe on a reusable portion.
A cassette comprising a fluid conduit including at least two sensor elements adjacent the conduit having the ability to permit both temperature and electrical conductivity sensing of fluid passing through the conduit, wherein the sensor elements are adapted for interconnection with a sensing probe comprising at least one sensor configured to measure temperature, and at least one lead configured to transmit electrical conductivity.
A method for determining temperature and electrical conductivity of a subject media using a cassette containing at least one sensor element adjacent a conduit capable of carrying said media, said method comprising the steps of:
A sensing system for sensing subject media in a fluid path in a cassette comprising:
A cassette comprising a pump chamber, a diaphragm associated with the pump chamber, and a fluid conduit including at least one sensor element adjacent the conduit having the ability to permit both temperature and electrical conductivity sensing of fluid passing through the conduit, wherein the sensor element is adapted for interconnection with a sensing probe.
A fluid pumping cassette comprising at least one pump, a fluid conduit and at least one well for transmitting temperature and permitting electrical conductivity sensing of fluid passing through the conduit, wherein the at least one well is adapted for interconnection with a sensing probe.
A method for determining temperature and electrical conductivity of a subject media using a cassette comprising a pump chamber, a conduit for carrying said media, and at least one sensor element adjacent the conduit, said method comprising the steps of:
