Intrinsically safe circuit [ edit ] An intrinsically safe circuit is designed to not be capable of causing ignition of a given explosive atmosphere, by any spark or any thermal effect under normal operation and specified fault conditions.
Unlike ATEX which uses numbers to define the safety "Category" of equipment (namely 1, 2, and 3), the IEC continued to utilise the method used for defining the safe levels of intrinsic safety namely "a" for zone 0, "b" for zone 1 and "c" for zone 2 and apply this Equipment Level of Protection to all equipment for use in hazardous areas since ...
In the technical specification 2-WISE [3] the 2-wire intrinsically safe Ethernet is defined. The intrinsic safety barrier is an electronic circuit at each output or input of a switch or instrument. It prevents ignitable electric energy from reaching the connector. The intrinsic safety barrier is separate from the communications circuit (PHY).
(Kletz originally used the term intrinsically safe in 1978, but as this had already been used for the special case of electronic equipment in potentially flammable atmospheres, only the term inherent was adopted. Intrinsic safety may be considered a special subset of inherent safety). In 2010 the American Institute of Chemical Engineers ...
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
U.S. Surgeon General Dr. Vivek Murthy warned in a recent advisory about alcohol use increasing cancer risk. The advisory notes that alcohol can increase the risk of throat, liver, esophageal ...
Two of the most powerful forces in the AI industry are set to collide this year: Elon Musk and OpenAI's Sam Altman. Here's what you need to know.
The high cost and limited coverage for obesity medications is driving many people to seek alternative treatments or other options that might not be safe, Fitch said. "There's a lot of shady stuff ...
