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.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
