ABSTRACT:
A temperature sensor is formed with a metal substrate at least a portion of which is coated with a layer of porcelain enamel. At least one conductive element is deposited on the coated portion of the substrate in such a manner as to provide a first sensor configuration for sensing temperature as a function of the resistance of the conductive element itself. This conductive element in operative combination with the porcelain enamel layer and the metal substrate provides a second sensor configuration for sensing temperature over a second temperature range as a function of the resistance of the porcelain enamel layer.
