Liquid Helium Transfer Line
AMI's high-efficiency, superinsulated, and vacuum-jacketed transfer line is designed for helium
transfer between standard helium storage dewars and magnet system dewars. The transfer line is
manufactured with a 60 inch flexible section and 60 inch dewar legs. An AMI
liquid helium level sensor
is contained in the lower 22" of the end of the transfer line which inserts into the liquid
helium storage dewar.
As the level in the storage dewar decreases to 22" or less from the end of the transfer line, an instrument connected
to the integral sensor will give an accurate indication of the helium liquid level for the remainder of the transfer.
The sensor is compatible with all AMI liquid helium level instruments. Construction is such that the sensor is field
replaceable should it ever need service. Each transfer line comes standard with 25 feet of interconnecting cable, integral
sensor, and a vacuum evacuation valve. Please specify which AMI instrument will be used in conjunction with the transfer
line to ensure the correct mating connector is furnished. When used with the affordable, hand-held Model 150A, you have
an incredibly versatile liquid helium transfer system.
