What is claimed is: 1. A cryogenic fluid distribution device, comprising: a fluid flow passage for distributing cryogenic fluid to an apparatus; an overflow passage positioned downstream of the apparatus; and a sensor coupled to the overflow passage, the sensor having an active component for determining if fluid is present in the overflow passage wherein the active component is a light emitting diode. 2. A cryogenic fluid distribution device, comprising: a fluid flow passage for distributing cryogenic fluid to an apparatus; an overflow passage positioned downstream of the apparatus; and a sensor coupled to the overflow passage, the sensor having an active component for determining if fluid is present in the overflow passage, wherein the sensor includes a body having a through passage therein defining a flow area for fluid, the sensor further including a hole intersecting with the through passage. 3. The device according to claim 2, wherein the active component is positioned within the hole and impinges into the through passage. 4. The device according to claim 3, wherein the active component is a light emitting diode. 5. An apparatus for distributing cryogenic liqiuid to a cooled device, comprising: a cryogenic liqiuid reservoir having an inlet and an outlet; a cooled device having an inlet and an outlet; a supply passage connecting the reservoir outlet and the device inlet for delivery of a cryogenic liqiuid from the reservoir to the device; a valve coupled to the supply passage and operable for controlling a flow of the cryogenic liqiuid within the supply passage; an overflow passage connected to the device outlet; and a sensor coupled to the overflow passage, the sensor having an active component configured for determining if cryogenic liqiuid is present in the overflow passage, wherein the active component is a light emitting diode. 6. An apparatus for distributing cryogenic liqiuid to a cooled device, comprising: a cryogenic liquid reservoir having an inlet and an outlet; a cooled device having an inlet and an outlet; a supply passage connecting the reservoir outlet and the device inlet for delivery of a cryogenic liqiuid from the reservoir to the device; a valve coupled to the supply passage and operable for controlling a flow of the cryogenic liquid within the supply passage; an overflow passage connected to the device outlet; and a sensor coupled to the overflow passage, the sensor having an active component configured for determining if cryogenic liqiuid is present in the overflow passage wherein the sensor includes a sensor body, the sensor body being configured to define a fluid flow path through the sensor body; and a recess opening into the fluid flow path. 7. The apparatus according to claim 6, wherein: the active component is positioned within the recess. 8.
