Abstract
A temperature-sensitive resistance element comprises an alumina substrate having terminals and a sinuous temperature-sensitive resistance layer thereon. The layer and terminals are formed of electroplated palladium which has been recrystallized.
Claims9
A temperature-sensitive resistance element, comprising an electrically insulating substrate supporting a temperature-sensitive resistance layer wherein said temperature-sensitive resistance layer is recrystallised electroplated palladium.
A method of manufacturing a temperature-sensitive resistance element characterised by the steps of providing on an electrically insulating substrate an electrically conducting film which adheres to said substrate, providing an electroplated palladium layer having the desired pattern on said electrically conductive film and then heat treating said electroplated palladium layer at a temperature such as to recrystallise the palladium.
