LumaSense Technologies Announces the Release of Luxtron Quality Probes(TM) to the Utility Industry

New Quality Probe is Industry's Most Rugged and Cost Effective Fiber Optic Solution
to Control Transformer Loading and Performance

May 22, 2008 - Santa Clara, CA - LumaSense Technologies (formerly Luxtron Corporation), a leading provider of temperature and gas sensing solutions to the utility, clean technology, medical, and industrial sectors, today announced a new addition to their extensive line of fiber optic temperature measurement probes. LumaSense has developed a new Quality Probe(TM) designed for accurate temperature measurement in high voltage applications, in particular winding hot spot measurement / temperature measurement in Power Transformers. The Quality Probe incorporates LumaSense's drift-free, calibration-free characteristics, patented Fluoroptic® Technology, and is immune to RF, EMI and Microwave interference.

The Quality Probe complements LumaSense's market leading Rugged Probe(TM), which has been used in the industry for over 25 years and is known for its strength and durability. The Rugged Probe currently has a 95% installation success rate without breakage issues. The Quality Probe boasts many of the Rugged Probes' advantages, but was designed to provide the marketplace with a cost effective alternative to the Rugged Probe. While the LumaSense Rugged Probe is the strongest fiber optic available in the market today, LumaSense's new Quality Probe will provide the industry with more ruggedness than other solutions, at a better price. Other new design features in the Quality Probe include improved oil circulation, state of the art sensor positioning mounting and strain reliefs in the probe itself to improve durability.

"We have successfully completed extensive high voltage testing of the new Quality Probe that confirmed the probes function and durability in the high temperature / high stress environment of an operating transformer," said Michael Franchek, Vice President of Technology and Innovation for Weidmann Electrical Technology, Inc. Weidmann has worked with LumaSense for more than 20 years in testing and design improvements in fiber optics, and is considered a major supplier of transformer insulating materials on a global basis.

"LumaSense has provided fiber optic temperature measurement in transformers for 25 years, and we have been installed in almost 2,000 transformers throughout the world. With the costs and lead times of transformers rising and the increasing electrical demand globally, transformers are becoming more and more of a critical asset," said, Brett Sargent, Vice President of Sales for LumaSense Technologies. "The Quality Probe gives us the design and cost advantage necessary to apply fiber optic temperature measurement into smaller transformers globally, thereby providing our customers the best technology to monitor and control transformer loading and performance."
