Abstract
A non-invasive temperature monitoring apparatus used in association with a guided wave member that may be for the purpose of sterilization and that is adapted for microwave heating of a substance that is absorptive at microwave frequencies and that is held in some type of container or connector that is transparent at microwave frequencies. The apparatus comprises a length of waveguide. A coupling aperture is defined in the guided wave member. The length of waveguide is supported with one end thereof about the coupling aperture. A microwave radiometer detection circuit is also coupled from the length of waveguide for detecting on a continuing basis the temperature of the substance which is usually liquid being heated by the microwave energy.
