Abstract
A temperature sensor (1) having a thick or thin film forming a resistance temperature sensing element (13c), a thermocouple (13a, 13b) or a resistance temperature device (13d) applied to the outer surface of one end (5) of a dielectric, cylindrical support (3) having a continuous circumferential protuberance (11) about the middle portion (9) thereof which can be engaged by a metal fixturing shell (33). Film type electrodes (15) and (17) extend upwardly along the outside of the dielectric support to terminal grooves (28) on the other end (7). A dielectric coating (29) is applied over the electrodes (15) and (17) to provide electrical isolation from the metal shell (33). A coating (29") may also be applied over the sensors (13) to reduce corrosion and abrasion and to provide electrical insulation.
