What's the difference between a gas alarm and a smoke alarm?"
Ion smoke alarm has an ionization chamber, ion chamber used radioactive elements - 241 am (Am241), the strength of about 0.8 micro Curie around in the balance of electric field under normal conditions, when there is smoke into the ionization chamber will destroy this balance, the alarm circuit detects the concentration exceeds the threshold will alarm.
Smoke alarm, a kind of alarm, common in life, the world's most commonly used smoke alarm, is the photoelectric smoke alarm and ionization smoke alarm.
Gas alarm is gas leak detection and alarm instrument. When the gas leak in the industrial environment, gas alarm detect gas concentration reaches the critical point of explosion or toxic gas alarm settings, alarm will be issued a warning signal to remind staff to take safety measures, gas alarm is equivalent to the automatic fire extinguisher that can be installed, drive exhaust, cutting, spraying system, prevent the occurrence of explosion fire poisoning and accidents, to ensure safety in production. Gas alarms measure all kinds of gas concentrations. Often used in chemical plants, oil, gas stations, steel plants and other places where gas leaks.
Photoelectric smoke alarm within an optical maze, equipped with infrared tube and infrared receiving tube does not receive the infrared light emitted by the infrared emission tube when the smoke, when the smoke into the optical labyrinth, through reflection and refraction, receiving tube receives infrared light, intelligent alarm circuit to determine whether exceeds the threshold, if it exceeds the alarm
