SENSORS:Kavlico recently introduced a rugged, aerospace-grade differential pressure (DP) sensor for monitoring pressure drop across a turbine engine style inlet air filter, also known as an inlet barrier filter. The DP sensor monitors filter health by detecting increases in pressure across the filter element. The DP sensor incorporates a piezo-resistive sense element and is available in pressure ranges of 0-1, ±1, ±5 and ±10 PSID, with other options available. Other features include an operating temperature range of -40 to 125C with a storage temperature of -55 to 150C, an accuracy of ±1.5 percent of full scale over the operating temperature and an operating voltage of 5 to 15V dc. The lightweight device (<6.5 oz) is rugged by design and has a housing constructed of an anodized aluminum with an MTBF of 300,000 hours at normal operating temperature. The DP sensor typically provides an output of 50 mV at 10V dc excitation.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
