Systems and methods of implementing an electrode for cooking medium quality measurement

摘要

A fryer measures cooking medium quality, and includes a cooking vessel configured to store a cooking medium, an electrode plate completely immersed in the cooking medium, an insulator comprising a first side and a second side, wherein the first side of the insulator is fixed to the electrode plate, and a second side of the insulator is attached to a wall of the cooking vessel, a guard ring fixed to the cooking vessel and surrounding the electrode plate and insulator. The guard ring extends further away from the wall of the cooking vessel than the electrode plate. A size of a gap between the guard ring and the electrode plate is based on a height, a width, and a thickness of the electrode plate and substantially defines a gain of the electrode. A signal conditioning circuit measures the conductivity of the cooking medium applied to the electrode.

主权项

1. An electrode unit for use in a fryer system, the electrode unit comprising:
an electrode plate comprising a first side and a second side opposite the first side, the electrode plate configured to be completely immersed in cooking medium, the electrode plate having a height, a width, and a thickness; an insulator formed on the first side of the electrode plate and covering a surface of the electrode defined by the height and the width; a guard ring surrounding the electrode plate, wherein the guard ring is positioned to form a gap between the guard ring and the electrode plate in the height and the width directions, wherein a size of the gap is defined at least by the height, width, and thickness of the electrode plate, and the gap substantially defines a gain of the electrode; and the second side of the electrode plate is a smooth polished surface.
