ABSTRACT:
Devices and methods for contactless heating of a fluid in a chamber using a high frequency alternating potential are described. At least two electrodes are coupled to the chamber such that the alternating potential is coupled to the fluid inside the chamber and heats the fluid. A control loop derives a signal from the alternating potential and uses the signal to control the alternating potential. The devices and methods described determine temperature and/or conductivity of the fluid using the signal.
