RAPID RESPONSE SENSOR HOUSING

摘要

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.

1. A sensor assembly comprising:
a housing comprising a unitary body having a proximal end portion and a distal end portion, the distal end portion defining an internal cavity and the proximal end portion defining a plurality of internal passageways that extend and open into the internal cavity, and a thin film resistive temperature device (RTD) disposed within the internal cavity, the thin film RTD having a pair of lead wires that extend from the thin film RTD through at least a subset of the plurality of internal passageways.
