Description
technical field [0001] The invention relates to a device and method for quickly measuring the resistance temperature coefficient of a heating element. Background technique [0002] At present, the heating element used to heat non-combustible appliances is mainly composed of a substrate and a resistance heating element, and when the temperature value of the resistance heating element rises, the resistance value of the resistance heating element will be generated according to its own temperature coefficient of resistance (TCR). Therefore, it is necessary to accurately grasp the value of the temperature coefficient of resistance of the resistance heating element in order to have a full understanding of the heating characteristics of the heating elements used to heat non-combustible appliances. At this stage, the method for determining the temperature coefficient of resistance is mainly the oven method, that is, the heating element is passively heated to the temperature values ...
