摘要： A fluid sensor probe such as a temperature probe uses heat shrink tubing to seal and provide strain relief at a proximal end of the probe. The heat shrink tubing uses a layer of hot melt adhesive along its inside surface to form a strong bond and hermietic seal. The heat shrink tubing is applied as an inner tubing around circuit wires extending into the probe and as an outer tubing around the inner tubing and around the proximal end of the probe housing. Together the inner tubing and the outer tubing can hermetically seal a substantial gap between the probe housing and the circuit wires. In a fast response probe, prior to closing the distal end of the probe housing with an end wall, openings are punched in a side wall of the probe housing against a mandrel. The openings permit fluid flow to contact the sensing element within the probe housing. Heat shrink tubing can be used to seal the circuit wires and prevent leakage.

摘要： A multipoint temperature sensor for measuring fluid temperature in a duct includes multiple thermistors of equal resistance, spaced apart in a circuit. Each thermistor has a positive lead and a negative lead for connecting electrically with the circuit. Wires connect the thermistors such that half of the thermistors are placed in parallel with the other half of the thermistors. The total number of thermistors in the circuit is a perfect square. Shrinkwrap fits over the thermistors and the leads. Tabs disposed on bridging clips bend around the shrinkwrap and the wires on either side of each thermistor such that the tabs do not overlap the leads. All the wires between adjacent thermistors are contained in a single, plenum rated sheathing.

摘要： A thermowell adapter secures a sheathed and flanged sensor within an internally threaded thermowell. The thermowell adapter has a head and a body extending from the head. The body of the thermowell adapter has external threading for mating with the internally threaded thermowell. A passageway within the head and body defines an axis coaxially with the external threading. The sheathed and flanged probe extends within the passageway such that a sensing element of the sheathed and flanged probe extends into the thermowell. An axial securement on the head prevents the sheathed and flanged probe from moving axially in the passageway. A rotational securement that is separate from the axial securement interacts in a mating relationship with squeeze locations on the sheathed and flanged probe to prevent the probe from rotating about its axis in the passageway.
