Type of article: Article
Summary
THIS ARTICLE DESCRIBES THE DESIGN FEATURES, CONSTRUCTION, AND OPERATION OF A LIQUID-NITROGEN LEVEL CONTROLLER WHICH CAN BE USED CONTINUOUSLY OVER A PERIOD OF SEVERAL WEEKS. LIQUID LEVEL IS SENSED BY PAIRS OF THERMISTORS MOUNTED ON A DIP STICK. REPLENISHING OF LIQUID NITROGEN IS ACHIEVED AS A RESULT OF SELF-PRESSURIZATION OF A TANK CONTAINING THE CRYOGEN. THE TRANSFER SYSTEM ENSURES A RIPPLE-FREE LIQUID SURFACE DURING THE REPLENISHING OPERATION. THIS LEVEL CONTROLLER HAS BEEN A PART OF A CRYOSTAT FOR DIFFUSION MEASUREMENTS IN LIQUEFIED INERT GASES.
