METHOD FOR ADJUSTING TEMPERATURE COEFFICIENT OF RESISTANCE OF TEMPERATURE-MEASURING RESISTIVE ELEMENT

摘要

There is disclosed a method for adjusting the temperature coefficient of resistance (TCR) of a temperature-measuring resistive element comprising an electrically insulating base and a platinum film formed on the base. The platinum film is formed by sintering an organic platinum compound. The temperature coefficient of resistance (TCR) is adjusted by controlling either the temperature at which the platinum film is heat-treated after the formation of the platinum film or the thickness of the platinum film.
