Measuring down to 10 ppm as far as 1 km away
When welding joints in long tube line or pipeline sections, it may not be practical to measure the purge gas exhaust close to the weld.
Measuring purge gas exiting in the joint gap is also unsatisfactory because of the the oxygen being drawn in from outside and other variable factors.
HFT® has developed an answer to this difficulty, namely a sensing head that can be fitted onto the purging system, directly at the weld location and will measure oxygen level in the purge gas and transmit the information electronically to the remote monitor and operator that may be up to 1 km away.
In this way, the operator can be certain that the weld purge reading is correct and that the joint will not be adversely affected by oxidation.
Portable ‘handy’ Purge Monitor, reading from 1000 ppm down to 1 ppm (accurate to 10 ppm).
The PurgEye® 1000 Remote, now with PurgeNet™ is equipped with a stainless steel sensing head, which connects onto any Inflatable or mechanical Tube, Pipe and Pipeline Weld Purging System, producing accurate readings up to 1 km away from the weld.
The sensing head and the integral electro-mechanical pump are powered by the data cable, so only one cable is required. The sensor head is small enough to fit inside pipes from 1” (25 mm) diameter, upwards and is easily manoeuvred through pipes.
