Helium Level Gauge

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:

a) 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.

b) 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 Probes

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.
