ALARM DEVICE FOR SENSING GAS QUANTITY WITHIN PRESSURE VESSEL |
摘要 |
Disclosed is an alarm device for sensing an amount of gas within a pressure vessel (10) in which high pressure liquefied gas or liquid is charged such as, for example, an LPG tank used in general housings, a gas tank installed on LPG vehicles, a tank lorry for storing or carrying high pressure gas, a liquefied oxygen tank, a refrigerating pressure vessel and the like, to thereby inform a user that the pressure vessel (10) should be exchanged or recharged to be previously supplied with the shortage of the liquefied gas. The alarm device includes: a sensing unit (20) (a unit serving as a proximity switch, a photo-electric switch, an optical sensor, a magnetic sensor, an optical fiber, an oscillator and so on, or a unit being capable of performing other sensing operations) which is installed within a pressure vessel (10), for sensing an amount of gas stored in the pressure vessel (10); a transmission line (30) which is connected to the sensing unit (20), for transmitting a sensing result of the sensing unit (20); and an alarm unit (40) which is connected to the transmission line (30), for generating an alarm in response to an output signal of the transmission line (30). |
