Process Sensing Technologies (PST), Ely, Cambridgeshire, UK, offers an oxygen analyser for inertisation applications in Additive Manufacturing, the Ntron SIL102 Oxygen Analyzer. The low-cost analyser can be configured for SIL 1 or SIL 2 applications with the addition of a second sensor; this complete system (analyser and sensor) meets the requirements of IEC 616598 SIL2.
Materials used in metal Additive Manufacturing (e.g., aluminium, titanium and their alloys) are combustible even in their smallest particulate form. As the AM process itself generates dust, a fire or explosion can result in an oxygen environment when these particles come into contact with an ignition source. With a measurement range of 0-25% O2, Ntron SIL102 Oxygen Analyzer aims to negate this risk with safety-critical process control applications.
The machine features three configurable alarm settings via a four-button user interface and is suitable for harsh process applications. All resultant analysis is displayed clearly via an LCD screen.
