Hi All,
I have just acquired two glass tubes, just over 6" long and 0.6" dia max with electrical connections at their ends.
The main tube is marked CE-122 Active Element Hard Glass, the other one is marked Compensator Element.
The internal structures appear to be identical - two fine wires on a suspension mechanism.
The Compensator may be evacuated, and has a getter has been fired to remove any trace of Oxygen (?), the usual silver deposit is present.
The Active element has an open end and was attached to a (sample ?) feed from pump mechanism via a rubber hose.
Each unit has two wires attaching to the top and enter the tube via hermetic seals.
DC resistance of each is around 4 ohms and do not appear to be very temperature sensitive.
The piece of the equipment that they were attached to did have an Ultra Violet warning, so presumably UV is part of the process...
Any ideas what type of gas these might be used to detect ?
Many thanks,
Mark
