Connect Direct to a Weld Purge Monitor®

During Weld Purging, while the value of Oxygen present, is being measured by a Weld Purge Monitor, welding and QA personnel, may frequently may need to measure the Dew Point Moisture to prevent the gases including oxygen, hydrogen and nitrogen from being absorbed into a weld joint.

The HFT® PurgeNet™ Dew Point Purging Gas Moisture Sensor Accessory™, is that value where condensation begins and any water in the welding environment, will condense on the material being welded, which can affect the weld properties significantly.

Huntingdon Fusion Techniques Ltd has a Dew Point Sensor in its product line that can be used in conjunction with our range of 1 ppm Weld Purge Monitors®.

It is not necessary to purchase a separate, expensive Dew Point Meter, as NEW PurgeNet™ Dew Point Purging Gas Moisture Sensor™ can simply be connected to and integrated with the Weld Purge Monitor® via the PurgeNet™ lead.

Available for use with the following Weld Purge Monitors® (1 ppm with accuracy to 10 ppm):

• PurgEye® 200
• PurgEye® 500 Desk
• PurgEye® 600
• PurgEye® 1000 Remote
• PurgEye® 1500 Site

Accurate Dew Point Measurement

The HFT PurgeNet™ Dew Point Purging Gas Moisture Sensor Accessory™ is designed to fit any of our Weld Purge Monitors® that read down to 1 ppm (accuracy to 10 ppm). 

Connection is made via the PurgeNet™ lead that is supplied as standard with these models.

Power Requirement

1 watt, powered from PurgeNet™ lead.

Output

Dew point data will be output to supporting Weld Purge Monitor® for display and Data Logging via PurgeLog™.

Data is displayed on the OLED screen of the PurgEye® Weld Purge Monitor® in split format so both oxygen (O2) and moisture (H2O) content are shown as ppm value.

See what our Users have to say......

The kit worked great, thanks again for letting us trial it.

The Dew Point Purging Gas Moisture Sensor™ was dropped off with our goods out team yesterday and should be back with you today and the PurgEye unit will be sent back.

Thursday after I’ve done a little more playing. I’ll be looking to place an order for both next week, could you please provide a quote?

Thanks for the brilliant service you have provided so far.

Frequently Asked Questions

1.0 What is ‘Dew”?
Dew is expressed as drops of liquid water that condense from the atmosphere and onto any solid surface like metal.

2.0 What is ‘the Dew Point’?
The dew point is the temperature in ºC or ºF at which air is saturated with water vapour (also referred to as humidity). Below the dew point, water will begin to condense on solid surfaces in the welding environment.

3.0 How does water moisture affect the quality of the weld joint?
Under arc conditions, water is broken down into hydrogen and oxygen in atomic form which, when present in weld metal, cause porosity and are known to create cracking in the weld joint.

4.0 Why should I use a Dew Point Purging Gas Moisture Sensor™?
Using the PurgeNet™ Dew Point Purging Gas Moisture Sensor™ while welding is the easiest method for indicating when water will condense on solid surfaces in the welding zone. Water can form as moisture on metal surfaces while welding and it is important to be able to measure ‘Dew Point” while welding lengthy critical joints as conditions can change during the welding process.

5.0 How does the Dew Point Purging Gas Moisture Sensor™ give readings?
The PurgEye® Dew Point Sensor accessory has been designed to integrate with most of the Argweld® Weld Purge Monitors® via the PurgeNet™ lead that is supplied with them, thereby giving values and water present on the same screen. In this way, the user is not forced into the purchase of an expensive, separate Dew Point Monitor that will give its reading elsewhere.

6.0 Which Weld Purge Monitors® are compatible with the Dew Point Purging Gas Moisture Sensor™?
The PurgeNet™ Dew Point Purging Gas Moisture Sensor™ is compatible with the PurgEye® 200, 500 Desk, 600, 1000 Remote and 1500 Site.
