Abstract
The invention relates to a carbon dioxide fire extinguishing device comprising a capacitive measuring device (11) which is calibrated for a temperature range above and below the critical temperature of carbon dioxide and which is used to detect the amount of gas loss from a carbon dioxide pressure tank (10). The carbon dioxide fire extinguishing device comprises an outlet valve in which the capacitive measuring probe (12) is integrated in such an advantageous way that the outflow resistance of the extinguishing gas is hardly increased at all.
Claims16
A carbon dioxide fire extinguishing device comprising:
- a carbon dioxide pressure cylinder (10) for storing extinguishing agent;
- a device for detecting a gas loss from the carbon dioxide pressure cylinder (10);
- characterized
- in that the device for detecting a gas loss from the carbon dioxide pressure cylinder (12) comprises a capacitive measuring device (11) which is calibrated for a temperature range below and above the critical temperature of the carbon dioxide.
The device as claimed in claim 15, characterized in that:
- the upper insulating sleeve (110) is pressed against an end face (58) of the valve base (32). 17. The device as claimed in claim 15 or 16, characterized in that the lower fastening sleeve (116) comprises:
- a metallic core body (122), which is screwed onto the lower end of the rising tube (38′);
- and
- an insulator, which is arranged between the metallic core body (122) and the outer electrode tube (40′).
