LPG alarm has become an essential safety device in kitchens. It detects any leakage of LPG and blows alarm. LPG gas alarm is a must have safety device in modern day homes. LPG used extensively in kitchens for cooking. Moreover LPG is finding its place in bathrooms for water heating purposes as well.
Usually presence of petroleum gaseous compounds should be in non hazardous limits. These limits stated by Government statutory bodies. When gas leakage is beyond limit, the LPG gas alarm detects it and automatically blows alarm. Excessive LPG leakage can cause breathing troubles or even explosion (in some cases).
LPG alarm models:
LPG01 standalone model operates with inbuilt buzzer. On detection of LPG leakage the beeping sound heard. It is audible from anywhere with 10-20 meters
LPG02 model equipped with transmitter. A high volume siren receiver located at a different location from the kitchen. The siren sound is around 108db and is audible within 80-100 meters from the vicinity
LPG03 model contains high volume siren and contactor relay cutoff point. These alarm units are usually used near LPG pipeline etc. On an event of LPG leakage siren is blow, as well as relay energized. This contactor is then used to deactivate the LPG line by cutting of the valve. Hence, electrically LPG supply modulation is possible on leakage detection
LPG04 model interfaces with GSM transmitter for sending alarm signals over mobiles phones. These machine send alarm signals as SMS and missed calls to users. So even if you are not at home, you can still receive alarm signals from the on account of LPG leakage
We suggest to install LPG gas alarm system in closed premises. Especially places like kitchen etc. in houses or hotels or restaurants. In kitchen usually combustible gases finds an extensive usage in day to day life. This sensor is also able to detect other combustible gases like propane, smoke etc.
Earlier models of LPG gas alarms had LCD display. The LCD model of the LPG gas alarm indicates the concentration of LPG in air. The concentration unit here used is ppm (parts per million). On an average, 1,000 ppm is around 1,800 mg/m3
Basis for revised IDLH
Because L.P.G. may cause asphyxia [Proctor et al. 1988] at concentrations well above the lower explosive limit (LEL). The revised IDLH for L.P.G. is 2,000 ppm based strictly on safety considerations. i.e., being about 10% of the LELs of 1.9% for butane and 2.1% for propane.
