Moisture Contamination Monitoring in Compressed Air

Product catalog summary

Overview
The document discusses the importance of controlling oxygen, dew-point, and humidity in metal additive manufacturing to prevent oxidation and moisture contamination, which can compromise the quality of the final product. This is particularly crucial in industries like aerospace, defense, and transport.

The AM Process
Metal additive manufacturing involves creating 3D objects from CAD models using metal powder. This process allows for the production of complex shapes not possible with traditional methods. Controlling oxidation and moisture is essential to prevent build failures and ensure high-quality standards.

Quality Control Solutions
The document outlines various solutions for monitoring and controlling oxygen and moisture levels during the additive manufacturing process:

Oxygen & Moisture Monitors: Devices like OxyDew and SenzTX Luminox are used to monitor oxygen levels, while polymer moisture sensors are used for moisture control.
Safety and Reliability: Ntron's fail-safe solutions meet IEC61508 (SIL2 Capable) standards, ensuring safety and reliability with features like zirconia sensors and optical PPM oxygen transmitters.
Accuracy: Oxygen analyzers can detect as low as 1ppm O2, with rapid response times and a wide operating range. Dew-point measurement accuracy is ±2°C, with a range from -110°C to +60°C.

Complete Solutions for Additive Manufacturing
Ntron offers a range of OEM oxygen analyzers designed for integration into AM machine control systems. These analyzers are SIL2 capable and comply with IEC 61508 standards. When combined with humidity transmitters and environmental control systems, they provide a comprehensive solution for quality, safety, and efficiency.

Related Products
The document also mentions related products for enhancing additive manufacturing quality:

Hot Isostatic Pressing (HIP): Uses high temperatures and pressures with inert gases like argon to improve material properties.
Gas Analyzers: Devices like MultiDetek 2 and Minox i provide trace impurity measurements and oxygen monitoring.
Dew-Point Measurements: Michell Instruments offers dew-point transmitters for ensuring dryness in industrial processes.

Monitoring Systems
The Rotronic Continuous Monitoring System (RMS) consolidates data from various sensors to ensure maximum quality in additive manufacturing. It provides real-time data, alarms, and comprehensive reporting capabilities.

Conclusion
The document emphasizes the critical role of precise monitoring and control of oxygen and moisture in ensuring the quality and reliability of metal additive manufacturing processes. The solutions provided by PST Group and its partners are designed to meet the stringent requirements of industries relying on this technology.
