Abstract
A surface temperature sensor includes a thermally conductive surface contact means for contacting a surface to be thermally measured and a coil. The coil contains an insulated thermal sensing element in thermal contact with the surface contact means and provides support for the surface contact means.
Claims19
A surface temperature sensor, comprising:
- a thermally conductive surface contact member for contacting a surface to be thermally measured;
- and
- a coil containing and carrying an insulated thermal sensing element in thermal contact with the surface contact member,
- wherein the coil provides support for the surface contact member;
- and
- wherein a substantial portion of the coil is in thermal contact with the surface contact member such that the thermal sensing element is substantially isolated from a thermal gradient along the coil thereby substantially eliminating heat transfer error due to thermal shunting.
