A sensor assembly includes a housing having a body having a distal end portion defining an internal cavity and a proximal end portion defining a plurality of internal passageways. A micro-sensor is disposed within the internal cavity and exposed to the outside environment and an internal wall separates the internal cavity from the plurality of internal passageways. The micro-sensor abuts the internal wall.

Rapid response sensor housing

A sensor assembly is provided that includes a housing having a unitary body with a proximal end portion and a distal end portion. The distal end portion is open and defines an internal cavity exposed to an outside environment, and the proximal end portion defines a plurality of internal passageways that extend and open into the internal cavity. A thin film resistive temperature device (RTD), or other micro-sensor, is disposed within the internal cavity, the thin film RTD having a plurality of lead wires that extend through the plurality of internal passageways, and the thin film RTD being in contact with at least one wall of the internal cavity. The thin film RTD and the lead wires are secured within the housing by a thermal adhesive having a matched coefficient of thermal expansion with that of the housing and the thin film RTD substrate.

A sensor assembly includes a tubular housing having an inner surface defining an axial chamber and a temperature sensor disposed in the axial chamber and moveable along an axial direction of the tubular housing. The sensor assembly further includes a seal carrier movable with the temperature sensor, and a sealing member disposed around the seal carrier. The sealing member is in sliding contact with the inner surface of the tubular housing and hermetically seals an interface between the sealing member and the inner surface of the tubular housing.
