The LN2 Autofill System provides vital features for the successful maintenance of detectors at liquid nitrogen temperatures. The system has a sensor placed at the venting outlet of the dewar, this enables the system to cut off supply when overflow is sensed, rather than simply imposing a time limit on the fill. Should there be a shortage of liquid nitrogen, or a fault with the system, an audible alarm will sound and the system will telephone a preconfigured number to inform of the situation.
