New Lifetime Warranty Policy for Sensors

Sierra Offers Life Time Warranty for Immersible Flowmeters

MONTEREY, CA — January 25, 2010 —Sierra Instruments has announced that it will offer lifetime warranty coverage for the Dry-Sense™ sensors in all Sierra Immersible Mass Flow Meters. Sierra has incorporated their proprietary Dry-Sense™ technology into their products since the 1990’s and to their knowledge are the only company in the industry to back up their thermal sensor for life.

“We’re committed to the highest quality in all our products, and I think our latest actions prove that we’re thinking ahead for our customers’ long-term benefit,” says Scott Rouse, Sierra Product Manager. “We believe our patented Dry-Sense™ no-drift sensors are the best in the industry and we’re willing to stand by them for their lifetime.”
Sierra offers the lifetime warranty on all Dry-Sense™ sensors in the Sierra Model 640S, 670S and 780S (non UHP) Immersible Thermal Mass Flow Meters sold after January 1, 2010. 
Traditional sensors use organics like glues and epoxies to fix the sensor core in place. These “wet” sensors have organics that tend to crack and change composition over time, with a consequent loss of accuracy and need for re-calibration.  Sierra uses a proprietary manufacturing process and patented design that uses no organics, and thus is “dry”.  As a result, Sierra’s Dry-Sense™ sensors don’t drift over time, and thereby hold their original calibration. 

Sierra is the leading manufacturer of Thermal Mass Flow Meters in North America (Flow Research, 2009). A global leader in flow measurement and control for over 35 years, Sierra instruments designs and manufactures high performance flow instrumentation for gas, liquid and steam applications commonly found in the semiconductor, environmental, scientific research, petrochemical, energy, aerospace, and general manufacturing industries. With over 150 offices in 50 countries, Sierra is uniquely positioned to provide their innovative products and lifetime support for the leading companies of today and the growth enterprises of tomorrow.
