News ReleaseAir Products Discusses New Technology for Continuous Dew Point Monitoring of Sintering Atmospheres at POWDERMET 2017

June 08, 2017 Lehigh Valley, Pa.

Air Products (NYSE:APD) will discuss its new technology for continuous dew point monitoring of sintering atmospheres at POWDERMET 2017, the International Conference on Powder Metallurgy & Particulate Materials, on June 15 in Las Vegas. The company’s continuous dew point monitoring system helps manufacturers comply with industry quality standards and enables operators to plan for shutdowns and preventative maintenance of their furnaces.

Maintaining the appropriate atmosphere composition in the various zones of a sintering furnace is critical to achieving the desired delubrication and consistency of the sintered products. However, continuous monitoring of the dew point in the hot zone can be challenging as particulates and contaminants in the sample gas stream can accumulate in filtering systems and on sensors. Consequently, dew point readings can drift significantly, causing erroneous measurement and requiring frequent cleaning, recalibration and sensor replacement.

Air Products’ new continuous dew point monitoring system helps to mitigate these issues by incorporating design features, such as an automated self-cleaning and sensor calibration process, along with temperature control of the sensor and sampling system, to maintain accurate consistency of the measured dew point level. The system reports drifts and changes in dew point locally through monitoring and alarms or remotely through cloud server access, enabling furnace operators to address issues quickly and efficiently.

“Many Air Products innovations are inspired by our customers’ needs to address challenges in their day-to-day operations, enhance the quality of their products, and improve the efficiency of their processes,” said Tom Philips, applications engineer at Air Products. “Customers currently using our continuous dew point monitoring technology are finding that the system enables them uninterrupted use, without the need for calibration or maintenance of the sensors, and provides them with alerts on process drifts and maintenance needs before they become a major problem.”

Conference attendees are invited to learn more by attending Mr. Philips’ presentation, “Improved Reliability of Dew Point Measurements in a Sintering Furnace Atmosphere on a Continuous Basis,” on Thursday, June 15, at 8:25 a.m. as part of POWDERMET’s Furnace Atmosphere & Control technical session.
