Abstract : The patent describes a carbon composition resistor sensor that is lowered to a cryogen material which is in its cryogenic state. The current through the sensor is maintained constant by a regulator, and when a substantial change in the resistance of the carbon sensor occurs, an amplifier having its input connected across the regulator senses the change in the resistance of the regulator and causes a light to go on or off so as to indicate the top level of the cryogenic material.
