Abstract: An accurate and compact device for controlling heating of a material in the fluid chamber of a metal droplet jetting device includes a pair of sensors in contact with the material in the fluid chamber. By transmitting a controlled current through the material and detecting the generated voltage across the electrodes (or vice versa), a measure for the resistance of the material is determined. The resistance is temperature-dependent and a good indicator for phase changes in a material. By continually monitoring a resistance related parameter, the heating of the material may be efficiently controlled to maintain the material in its liquid phase during operation.
