Fixed temperature
WebApr 4, 2024 · Fixed temperature heat detectors have a set one that it recognizes before it sets off its alarm. This temperature is either 135°F (57°C) or 194°F (90°C). Depending on what type of building you’ll use it for, you will likely come across the 135 F more often. The higher of the two is used more often by businesses dealing with welding or steelworks. WebFeb 4, 2024 · A fixed temperature heat detector is a type of fire detector that is triggered when the temperature of the surrounding environment reaches a certain threshold. This threshold is typically between 135 and 165 degrees Fahrenheit. Fixed temperature heat detectors can be either mechanical or electronic.

WebJan 6, 2024 · The proof that is the subject of your post assumes the two devices are reversible, that is, they have the maximum possible efficiency for the cycle, regardless of the details of the cycle. It only seeks to prove that all reversible engines operating between two fixed temperatures have the same efficiency. This is the most common type of heat detector. Fixed temperature detectors operate when the heat sensitive eutectic alloy reaches the eutectic point changing state from a solid to a liquid. Thermal lag delays the accumulation of heat at the sensitive element so that a fixed-temperature device will reach its operating temperature sometime after the surrounding air temperature exceeds that temperature. The most common fixed temperature point for electrically connected heat dete…
