Oxygen Analyser Guarantees Quality and Safety for Heat Treatment Processes


Utilising an advanced coulometric sensing technology that delivers exceptionally accurate and stable oxygen analysis, the Servomex (UK) DF-150E protects batch quality and significantly improves plant efficiency for a range of reflow application processes.


Accurate to ±3% of reading / 0.5% of measurement range, the DF-150E is highly suitable to control O2 levels in surface mount soldering operations in reflow PCB ovens, which must be O2-free if the soldered joint is to be permanently sealed. An extremely versatile unit, the DF-150E can be configured to operate as a single or three-range analyser to meet specific process needs.


In reflow ovens, heat is transferred to assemblies by radiation using Nitrogen (N2) to establish an O2-free environment that minimises oxidisation of surfaces to be soldered. The DF-150E uses non-depleting coulometric E-sensor technology to ensure accuracy with no sensor drifting and no false low readings, protecting against


oxidisation. This no fail performance is crucial, as a false O2 reading can waste thousands of dollars in scrapped final product, schedule disruption or cause safety issues when using N2 or mixtures using N2 as a blanketing gas.


The DF-150E's non-depleting technology enables the O2 sensor to cope with short time exposure to ambient air, with options for temporarily disabling the sensor to enable longer exposure to ambient air - a capability not possible with traditional electrochemical sensors, where extended exposure to air quickly damages the cell.


The DF-150E is factory calibrated and reduces cost of maintenance with a five-year sensor warranty that requires only an annual SPAN calibration and no programmed cell replacement. With just a single instrument calibration per year, the reduced maintenance costs and its peerless stability have found favour with furnace manufacturers, quality product managers, process engineers and product development engineers alike.


Every DF-150E is custom configured under ISO-9001 controls to meet the customer’s precise specifications and calibrated to standards traceable to NIST and operated for several days to ensure flawless out-of-the-box performance. The analyser also delivers near-instantaneous response to O2 change – typically taking less than 10 seconds to read 90% of a step change.


The flexibility of the DF-150E means it can be easily integrated into multiple zone sample systems using a manual or automatic sequencing system. This makes it ideal for OEM furnace manufacturers who supply analysers as an option or as standard for the end-user; heat treatment contractors; and on-site or laboratory processes providing 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 Carbon Dioxide (CO2), Hydrogen Sulphide (H2S), Nitrogen Oxide (NOX) and Sulphur Dioxide (SOX).

By means of the innovative mounting concept FLOW-SMS a variety of components for mass flow and pressure measurement and control can be assembled to constitute a very compact gas delivery system. On a lightweight but still rugged mounting rail system one or more mass flow (or pressure) sensor/control modules can be combined with mixing chambers, (pneumatic, electrical or manual) shut-off valves, filters or any other functional module as per customer's request. Flow ranges can be selected between approx. 5 mln/min up to 50 ln/min or even higher. In case a pressure sensor or controller is included, the pressure range can be chosen between 0-100 mbar and 0-10 bar absolute or gauge.


The three major criteria for development – space efficiency, service friendliness and flexibility of expansion or modification – are realised within a compact, top-mount design. As a standard, FLOW-SMS systems can be configured for up to nine


channels. In agreement with the customer, Bronkhorst High-Tech (UK) will supply the completely assembled systems tested on functionality and leak tightness, ready to plug and perform. Customers will not only benefit the space efficiency but also a reduction of labour for pipe installation and testing. By means of the customer’s flow chart, Bronkhorst will realise the “LEGO-principle” fluid delivery or mixing system - accurate, reliable and well documented.

It goes without saying that process interruptions are undesirable and very costly. Therefore it is sensible to use reliable and quality parts in the production process, avoiding the “penny wise, pound foolish” trap with cheaper, but unreliable instruments. Recognising this need for reliable and durable displays, Fluidwell (Netherlands) has always pursued excellence in quality and reliability. To support this claim, the warranty period for displays has now been doubled to two years.


“No, we are not expecting added cost, or to get more repairs returned as a result of prolonging the warranty period”, says Eric Rath, General Manager of the Fluidwell Group in The Netherlands,


with a smile on his face. “99.8% of the displays we ship out, are never seen back again, and of the 0.2% we get back, half are because of improper use. The decision to double the warranty period is a signal of goodwill and evidence of our trust in our products and to strengthen our reliability core value”.


The warranty period extension to two years is effective immediately and retroactive for displays purchased in the last two years. 27427pr@reply-direct.com
