Abstract
Abstract A thermometer probe comprises a temperature sensing element for sensing temperature of an object to be sensed, a conductor connected to the temperature sensing element for transferring the sensed temperature, an insulator for coating the conductor, and a water-resistant sheath for enclosing the temperature sensing element, the conductor, and the insulator. The opening end of the sheath is welded for enclosure of the temperature sensing element.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
180 words
A thermometer probe for sensing the temperature of a liquid, comprising: a temperature sensing element for sensing the temperature of said liquid; first and second elongated conductive members connected on opposing sides of the temperature sensing element for communicating temperature information, wherein the first conductive member is shorter than the second conductive member, and wherein the first conductive member and the temperature sensing element when joined together form substantially the same length as the second conductive member; first and second insulating members for coating the first and second conductive members, respectively; and an elongated water-resistant elastic sheath enclosing the temperature sensing element, the first and second conductive members, and the first and second insulating members, wherein the water-resistant elastic sheath has a distal end which is welded closed, wherein the water-resistant elastic sheath extends continuously from said distal end a distance substantially equal to the length of the elongated conductive members to at least a point remote from the temperature sensing element where no exposure to said liquid occurs, and wherein the water-resistant elastic sheath directly abuts the insulating members.
Claim 2
Dependent Claim
