Circulator - Wikipedia

Circulator - Wikipedia

A circulator is a passive, non-reciprocal three- or four-port device, in which a microwave or radio-frequency signal entering any port is transmitted to the next port in rotation (only). A port in this context is a point where an external waveguide or transmission line (such as a microstrip line or a coaxial cable), connects to the device.For a three-port circulator, a signal applied to port 1 .

How to Use Your New Sous Vide Immersion Circulator .

That's what the sous vide circulator does: It heats water to the perfect temp every time! To start, hook your immersion circulator over the side of the pot so that the circulator is submerged in the water. For the Joule, it's fine if the circulator touches the bottom of the pot; check your manual for guidelines on other circulators.
