Abstract
A sheathed and flanged temperature probe is formed using a cylindrical sheath and a flange of the same metallic material. The cylindrical sheath is closed on one end and open on the other, and has a length at least an order of magnitude greater than its outer diameter. The temperature sensing element is inserted into the sheath, leaving wires protruding from the open end of the sheath. The sheath may contain an epoxy in the closed end to insulate and stabilize the sensing element. The central portion of the sheath remains empty except for wires connecting the sensing element to the electrical leads. The open end of the sheath is sealed around two electrical leads, enclosing the temperature sensing element from ambient conditions. The flange member is formed from a single piece of metal, cold drawn using an awl to form a continuous sleeve having an axis perpendicular to the planar surface of the flange. The sheath is inserted into the sleeve. The flange is secured to the central portion of the sheath solely using a press crimper, pressing inward over a majority of the circumference of the sleeve, leaving crimp edges extending on opposite sides of the sleeve. At least one planar surface of the flange may be sealed with a gasket.
