Connecting the E5080 to a magnet system
E5080 Series Cryogen Monitor User Guide
Connections are made via the magnet cables / gas pipe as
required for the specific installation:
Magnet
Helium level cable
Helium gas pressure
pipe
Gas heater
Thermal sensor cable
Do not connect any cables to "PRESSURE", "AUX INPUT",
"RELAY OUT", or "LN2".
In E5084 mode, exhaust helium gas leaves the unit from gas
port B and can optionally be routed through a floating ball
flow gauge to give a visual indication of gas flow. You can
also use this port to route gas into a helium recovery
system.
Gas port C is used to measure the ambient atmospheric
pressure. On earlier units, atmospheric pressure is measured
directly within the enclosure of the unit.
