Low-Pressure Generator Makes Cleanrooms Cleaner

About this technology

Overview

Scientists at Kennedy developed a technique and equipment to perform qualification testing on new low-differential pressure transducers for cleanrooms in an accurate, cost-effective manner onsite. They used the Setra Model C264 as the test transducer. For qualification testing of the Setra, though, a portable, lower-cost calibrator was needed that could control the differential pressure to a high degree of resolution and transfer the accuracy of the Standards Laboratory testing to the qualification testing. Thus was born the low-differential pressure generator. Personnel at Setra Systems, Inc., came across the new technology while conducting a search for the same type of equipment that the staff at Kennedy had wanted. Setra then obtained rights to the patent. The Micro-CalTM Low Pressure Calibrator is now part of the only portable single-component transducer available on the market.
