The Liquid Nitrogen Sensor and Level Monitor (hereinafter referred to as the LN₂ Monitor) is designed for continuous monitoring of liquid nitrogen levels in a Dewar vessel with an installed HPGe detector, and for displaying the LN₂ level on the indicator.
Features
Display of liquid nitrogen level in percent, shown on a scale or digital indicator;
Activation of a color alarm when the liquid nitrogen level falls below the threshold value of 20%;
Activation of an audible warning signal when the liquid nitrogen level falls below the threshold;
Automatic muting of the audible signal when the level rises above the threshold or when refilling is detected;
Transmission of a control signal to refilling equipment (optional).
