Non-Intrusive Pig Signaller Devices
The Hi-T Magalert and Hi-T Ultralert are robust non-intrusive pig signaller devices that use “magnetic” and “ultrasonic” detection principles respectively to detect, signal and log the passage of pigs at critical points along a pipeline. The Hi-T Maglaert and Hi-T Ultralert devices can be used for both offshore and onshore installations.
The Hi-T Magalert and Hi-T Ultralert are ATEX compliant and are housed inside fully certified aluminium or stainless steel explosion proof housing suitable for use in Zone 1, Zone 2, Group IIA, IIB and H2 Areas.
The Hi-T Magalert and Hi-T Ultralert devices can log up to 100 events with time and date. All logged events can be viewed on a 70mm (2.7″) high visibility display incorporated in the main housing. Prior to clearing the history of logged events it is also possible to connect the devices to a PC and download all stored data.
Pig passages can also be signalled as they occur with ultra-bright LEDs which are incorporated into the main housing and are visible from up to 100m.
