Technical Data and Specification

PurgEye 1000 Remote Weld Purge Monitor Sensor Display Unit

Measuring range from 1,000 ppm down to 1 ppm (accurate to 10 ppm).

The PurgEye® 1000 Remote also supports the following:

  • Remote sensor head including electro-mechanical pump.
  • Two user settable limits for alarm and process control.
  • Relay contacts are included for monitoring the oxygen level.
    The contacts are no/nc (Normally open/normally closed) and volt free.
    They can be used to activate an alarm or switch a welding machine off and on again when the oxygen level rises above or falls below preset limits.
  • Sounder for out of range oxygen readings.
  • Key tones, to confirm button presses.
  • RS-232 port for connecting to a personal computer (PC).
  • Data logging facility, via PC.
  •  Machine status input (for data logging).
  • Small, light and portable.
  • Selectable display and language.

Range: 10 – 1000 ppm
Accuracy : + 25 ppm
Warm-up time: 2 minutes
Response time: 30 seconds
Reproducibility: < 15 ppm
Power consumption: Max. 18V

Use only weld purge hose leak tight quick disconnect fittings suitable for connecting 6 mm OD polyurethane tubing. Do not try to use other diameter tubing because it will not seal properly and will end up causing leaks.

The PurgEye® 1000 Remote Weld Purge Monitor® is simple to use, real plug and play.

The sensor A is connected to the exhaust of the purging device, which is located directly at the weld site.

The exhaust purge gas flows through tube A and is measured by the remote sensing unit B, which sends the results electronically back to the display unit C.

The sensing head B can be supplied with fixing brackets so that it can be fitted to an internal pipe clamp with purging seals or stand alone pipe weld purging system.

Dew Point Sensordew Point Sensor for accurately measuring the dew point.

During purging welders need to measure the oxygen content but also need to measure the ‘dew point’.

The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly.

We have recently added a Dew Point Sensor to our range that can be used in conjunction with our range of 10 ppm Weld Purge Monitors®, so rather than purchasing a separate, expensive Dew Point Meter, HFT®’s Dew Point Sensor that can be connected to the Weld Purge Monitor® via the PurgeNet™ lead.

The dew point sensor is designed to fit any of our Weld Purge Monitors® that read down to 1ppm:

- PurgEye® 600

- PurgEye® 1000
