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.
Claims17
A carbon dioxide fire extinguishing device comprising:
- a carbon dioxide pressure cylinder for storing an extinguishing agent;
- a device for detecting a gas loss from said carbon dioxide pressure cylinder;
- wherein said device for detecting a gas loss from said carbon dioxide pressure cylinder comprises a capacitive measuring device which is calibrated for a temperature range below and above a critical temperature of said carbon dioxide.
The device as claimed 5, wherein said outer electrode tube has an annular end face, which is pressed against an annular end face of said valve base.
The device as claimed 11, wherein:
- said insulating sleeve is screwed into said inlet bore.
