Delta F DF-150E Oxygen Analyser Guarantees Quality and Safety for Heat Treatment Processes


Crowborough, UK, - Offering exceptionally accurate oxygen (O2) analysis through unique coulometric sensor technology, the Delta F DF-150E from Servomex delivers heat treatment processes the measurement stability and reliability that guarantees exceptional batch quality and improves plant safety.

Offering both single range or 3 range options - ideal for furnace start-up and operation conditions - and exceptional accuracy of ±3% of reading / 0.5% of measurement range, the DF-150E utilises Servomex's unique, non-depleting E-sensor technology to ensure accurate results with no sensor drifting, no false low readings and no frequent calibration requirements. This produces a 'no fail' performance crucial to successful heat treatment processes, where a false O2 reading can waste thousands of dollars in poor batch quality or cause safety issues when using hydrogen (H2) or mixtures using H2 as a blanketing gas.

Able to measure O2 in a range of inert and modified atmospheres the DF-150E's exceptional ability to monitor low levels of oxygen means it can protect against oxidisation in a range of process conditions. This covers atmospheres in a wide range of heat treatment processes including reflow (which uses nitrogen), annealing and sintering (H2), batch annealing (H2 and N2) and brazing (inert gases).

Servomex's coulometric E-sensor offers a host of advantages over competitor techniques, with the technology's exceptional stability reducing maintenance costs through lower calibration requirements. The sensitivity of the measurement avoids the schedule disruption, waste and scrappage costs incurred by oxidized product, as well as ensuring plant safety is fully maintained when using H2 as a purge gas in sintering and annealing processes.

The flexibility of the DF-150 enables easy integration into multiple zone sample systems using a manual or automatic sequencing system to assure that a quality product comes out of the furnace. The DF-150E is therefore ideal for OEM Furnace Manufacturers who supply analysers as an option or as standard for the end-user customer, heat treatment contractors and on-site processes which provide treatment for end products in-house.

The DF-150E offers users a range of configuration options that enables the analyser to be built to their particular measurement requirements. Choices include CE Certification, a choice of Outputs, Flow Alarm, Sample Pump and Remote Sensor options. A unique acid gas sensor option also neutralises trace levels of acid gases in the sample including CO2, H2S, NOX and SOX.

Every analyser is custom configured under ISO-9001 controls, factory calibrated to standards traceable to NIST and tested for several days before shipping to ensure flawless performance.
