A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure that protects a radar antenna. [1] The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by ...
An induction heater is a key piece of equipment used in all forms of induction heating. Typically an induction heater operates at either medium frequency (MF) or radio frequency (RF) ranges. [1] Four main component systems form the basis of a modern induction heater. the control system, control panel, or ON / OFF switch; in some cases this ...
A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage ...
There are so many things to love about Bernese Mountain dogs. These gentle giants are loyal, caring, and patient with children. Their thick coat makes them ideal for colder climates, and their ...
The American Meteor Society received over 40 reports of a fireball sighting at around 11:15 a.m. ET over New York, New Jersey, Connecticut and a few other states in the US Northeast. The society ...
Electric heating. This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. [1]
Starring Daisy Edgar-Jones as Kate and Glen Powell as Tyler, two rival Tornado Alley storm chasers who begin to realize their passions overlap in more ways than one, Twisters builds on its ...
Catalytic heater. A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce calefaction (heat). [1] When the catalyst, fuel (e.g., natural gas), and oxygen combine together, they react at a low enough temperature that a flame is not produced. This process keeps repeating itself ...
