Huntingdon Fusion Techniques HFT® has introduced the PurgEye® 1000, a localised sensor with a long-distance cable. The new release displays the oxygen level in the welding zone on the Weld Purge Monitor® screen from 10, 50 or even 1,000 meters away from the weld.

The PurgEye® 1000 comprises a stainless steel housing with a sensing head that can be fitted onto any Pipe Weld Purging System or left in the welding zone and have the oxygen levels transmitted electronically to a monitor up to 1km away. 

“By using a remote sensing head, which can be fitted onto any Mechanical or Inflatable Tube and Pipe Welding Purging System from 1” diameter upwards, or even left in the welding zone, the oxygen level can then be measured directly at the weld location and the information will be electronically transferred to the monitor up to 1km away,” said Luke Keane, Technical Sales Manager for HFT®.

“With this capability, the operator can be certain that the weld purge reading is correct and that the join will not be adversely affected by oxidation and will be welded at the correct time without any risk of contamination, oxidation or ultimate failure,”

“The Purgeye® 100 is one of our five Weld Purge Monitors® to now feature PurgeNetTM, a networking device designed for communicating the current oxygen reading from the Monitor, to another piece of equipment, such as the visual warning accessory PurgeAlarmTM or a Dew Point Monitor with additional inter-pass temperature monitoring,” Keane continued.

The PurgEye® 1000 measures oxygen levels from 1,000 parts per million (ppm), down to 1ppm, ideal for welding metals such as stainless steels, duplex steels, titanium and zirconium where oxide free, zero colour welding are required.
