Huntingdon Fusion Techniques (HFT®), a weld purging products manufacturer, has launched an updated version of its PurgEye® 1000 Weld Purge Monitor, which enables operators to read weld purge gas levels from a distance.

The updated device makes it possible to immediately read gas levels from the underside of the welding joint from up to 1,000 metres away.

The sensor is secured and fixed inside the purging system itself, which is connected to the measuring instrument via a data cable. The purge reading is then sent back to the instrument instantly allowing operators to accurately monitor, and therefore avoid oxidation, of weld zones.

Luke Keane, Distributor Support for the UK-based business, explained, “By using a remote sensing head, which can be fitted onto any mechanical or inflatable tube and pipe weld surging system from 1” (25mm) diameter upwards, the oxygen level can be measured directly at the weld location and the information will be electronically transferred to the monitor up to 1km away.”

He added, “The PurgEye 1000 is one of our five Weld Purge Monitors® to now feature PurgeNet™, a networking device designed for communicating the current oxygen reading from the Monitor, to another piece of equipment, such as the visual warning accessory PurgeAlarm™ or a Dew Point Monitor with additional inter-pass temperature monitoring.”

The instrument was designed to eliminate timely reading results as a consequence of attempting to attain stable readings in normal weld purge systems. By enabling the sensor to be placed directly next to the weld purging site, HFT have facilitated this without compromising the user’s safety.
