Helium Level Gauge and Probe
Helium Level
Gauge
Cryogenic offers mains powered and optionally battery powered liquid helium level gauges to both measure and control liquid helium levels.
Two Electronics units are available as standard:
- HLG200 The front panel features a self ranging 3 digit LED display, 0 to 1100mm (1mm resolution). Switches are provided for on/off, probe type and pulse interval.
- HLG210 Similar to the HLG200
but offers additional control features. There are
three internally adjustable pre-set levels, easily set
by reference to the display. Two drive a 2-pole
change-over relay for power switching (e.g.; to drive
solenoid valves in auto refill systems). The third
provides a reference point, or can provide output to a
persistent mode switch or audio /visual
alarm.
Helium Level Probe
Standard probes consist of a superconducting element contained in a ventilated 2.1mm diameter stainless steel tube. The tube is terminated at the room temperature end with a 28mm long cap and 7 pin connector.
