Appl. No.:

17/825752

Inventors:

- Everett WA, US
Rong Ding - Lindon UT, US

David W. Farley - Orem UT, US

International Classification:

G01K 7/18
G01K 1/08
G01K 1/14

Abstract:

A temperature sensor includes a main body having a peripheral surface that extends along an axis between ends of the main body. A plurality of support structures are arranged along the main body and project from the peripheral surface of the main body transversely to the axis. A sleeve has a cavity defined by one or more sidewalls extending between first and second ends. The main body of the temperature sensor is positioned within the cavity. A platinum member having a length that extends along the main body is supported by a set of support structures of the plurality of support structures. In some cases, a seal member extends between the one or more sidewalls at the first end of the sleeve and seals the main body and the platinum member within the cavity. Measurement terminals may extend from the platinum member to an exterior of the temperature sensor.

Abstract:

A platinum resistance temperature sensor having a housing that contains a platinum member. The housing includes a first substrate having a first support and a second support spaced apart from an upper surface of the first substrate. The first support of the first substrate supports a first portion of the platinum member and the second support supports a second portion of the platinum member. Medial portions of the platinum member are suspended over the upper surface of the first substrate between the first support and the second support.
