Sensor apparatus systems, devices and methods

摘要

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.

主权项

1. A multi-fluid flow path containing sensing system for sensing subject media comprising:
a sensor manifold comprising a housing enclosing at least a first fluid flow path and a second fluid flow path which are fluidically isolated from each other during use of the sensing system, each of said first and second fluid flow paths having a fluid inlet port and a fluid outlet port, wherein the first fluid flow path of the sensor manifold is configured to receive a liquid via a first port and to expel the liquid via a second port located vertically above the first port, and wherein a third port above both the first and seconds port is arranged to vent gas that escapes from the liquid moving from the first port to the second port; and a sensor apparatus for sensing a conductivity of subject media in each of said first and second fluid flow paths, wherein the sensor apparatus comprises a separate group of conductivity sensors associated with each of said first and second fluid flow paths, each group of conductivity sensors comprising at least two conductivity sensing probes spaced apart from one another.
