Description

A liquid level sensing system for a double-walled viewing window enclosing a body of transparent shielding liquid comprises a thermistor whose tip is immersed in a portion of the liquid within an upward extension of the liquid filled chamber between inner and outer window panes. The extension is above the top edges of the windows. The thermistor is wired up to alarm equipment so that, in the event of a temperature change corresponding to interruption of contact between the liquid and the thermistor, alarm signals are generated. The window is intended particularly for a cave in which radioactive materials are to be handled remotely. (author)
