Ensuring Optimal Inert Atmospheres in Additive Manufacturing with OxyPro-XT

Why Oxygen Monitoring Matters in Additive Manufacturing 

In additive manufacturing, particularly with metal powders, maintaining an inert atmosphere is crucial to prevent oxidation and ensure the quality of printed parts. Even parts-per-million oxygen levels can compromise mechanical properties, reduce yield, and increase production costs in metal additive manufacturing. 

Risks of Oxygen Contamination 

• Material Degradation: Oxidation of metal powders such as titanium or stainless steel can lead to porosity, brittleness, and poor surface finish. 

• Yield Loss: Defective parts may require reprinting, increasing material waste and machine time. 

• Process Inefficiency: Unstable oxygen levels can trigger build pauses or machine cleaning cycles. 

Precision Oxygen Monitoring with OxyPro-XT 

The OxyPro-XT SMART Oxygen Transmitter offers reliable, plug-and-play oxygen monitoring for ultra-pure gas environments in additive manufacturing. Using zirconia diffusion-limiting SMART sensors, the transmitter provides long-life, high-accuracy measurement with minimal maintenance. 

• Detection down to 10 ppm O₂ 

• No calibration – pre-calibrated SMART sensors 

• Plug-and-play replacement reduces downtime 

• Fast response for real-time monitoring 

Key Features: 

• Measurement ranges from 10 ppm to 96% O₂, selectable per sensor. 

• No calibration required; pre-calibrated smart sensors ensure precise readings. 

• Analog (0…5 V, 4…20 mA) and RS485 Modbus RTU outputs for seamless process integration. 

• Programmable O₂ alarms/relays for process control and safety. 

Performance Highlights: 

• Fast response times (< 5 seconds, depending on sensor housing). 

• Sensor life up to 5 years (application dependent). 

• IP66-rated sensor plug and IP40 transmitter housing. 

• Operating temperature: +10…+100 °C (sensor head), +10…+50 °C (monitor). 

• CE compliant to EU machinery directive and EN 61010-1. 

Available Sensor Housings: 

• D0 (M16 Steel), D2 (M16 Aluminium), D3 (M18 Aluminium), B1 (TO8 Flange). 

• Available in multiple housings for direct integration into AM build chambers and powder-handling systems 

Key Benefits Across the Range: 

• Ultra-low detection limits down to 10 ppm oxygen for high-purity gas monitoring. 

• Plug-and-play SMART sensors reduce downtime and maintenance costs. 

• Flexible installation options: DIN rail mount, extension cables, multiple output types. 

• Robust design for cleanroom and controlled manufacturing environments.
