Abstract
A heater for use in fluid immersion heating includes a plurality of resistive heating elements, and a plurality sets of power pins electrically connected to the plurality of heating elements. Each set of power pins includes a first power pin made of a first conductive material, and a second power pin made of a second conductive material that is dissimilar from the first conductive material of the first power pin. The first power pin is electrically connected to the second power pin to form a junction. The second power pin is electrically connected to the corresponding resistive heating element. The junctions between the first power pins and the second power pins are disposed at different heights in order to sense a level of the fluid.
