What is the difference between a gas alarm and a smoke alarm?

January 10, 2022
The gas alarm is a gas leak detection alarm instrument. When the gas in the industrial environment leaks and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas alarm will send an alarm signal to remind the staff to take safety measures. The gas alarm is equivalent to automatic. Fire extinguishers and the like, can be installed to drive the exhaust, cut off, spray system to prevent explosions, fires, poisoning accidents, thus ensuring safe production. The gas alarm can measure various gas concentrations. It is often used in chemical plants, oil, gas stations, steel plants and other places where there is gas leakage.
Smoke alarms, a type of alarm, are common in life. The most commonly used smoke alarms in the world today are photoelectric smoke alarms and ionized smoke alarms.
The ion smoke alarm has an ionization chamber. The radioactive element used in the ion chamber is 镅241 (Am241), which is about 0.8 microcurie. It is in an equilibrium state of electric field under normal conditions. When there is smoke entering the ionization chamber, this balance will be destroyed. Relationship, the alarm circuit will issue an alarm when it detects that the concentration exceeds the set threshold.
There is an optical labyrinth in the photoelectric smoke alarm, which is equipped with an infrared pair tube. When the smoke is not smoked, the infrared receiving tube can not receive the infrared light emitted by the infrared emitting tube. When the smoke enters the optical labyrinth, the receiving tube receives the infrared through the refraction and reflection. Light, the intelligent alarm circuit determines whether the threshold is exceeded, and if an alarm is exceeded.
