Abstract

This paper describes a cryogen inventory control of liquid cooled HTS motors and generators. It is used to check inventory of neon in a system. One way of doing this is to use the G-force on the liquid and measure its temperature at the outside diameter.

Liquid Level Indicating Device for Cryogen Inventory Control of Liquid Cooled HTS Motors and Generators

    This paper describes a liquid level indicating device for cryogen inventory control of liquid cooled HTS motors and generators. It is used to check inventory of neon in a system. One way of doing this is to use the G-force on the liquid and measure its temperature at the outside diameter.

     We are currently thinking of using a manifold to allow for proper distribution of the liquid, by adding a finger to this manifold we should be able to detect a loss of liquid by a change in the finger tip temperature.

@ 1 3/8" High with starting temperature pressure @1.2 ATM 28 K

Tsensor = 32.84º K

OT = 1º @ 1" High

Tsensor = 31.9

     This should be easily measured with a Cernox resistor.

Note: Coil temp @ 1 3/8 high in tube is 3/8 high @R=8"

Tcoil = 29.5 K With Tsat (1.2 atm) = 27.65 K
