The Texas Instruments Sensors & Controls group has introduced a low-cost, hermetically sealed pressure transducer/transmitter, available in both 4-20 mA or voltage outputs. With electromagnetic compatibility (EMC) protection at levels to 100 V/m, the transducer also features vibration tolerance rated at 20g (up to 1 kHz), a wide operating temperature range of -40 to 135C, and pressure ranges from 50 to 750 psi. Applications include medical systems monitoring and pneumatics, HVAC regulators and compressors, pumps and flow systems used in process industries, and hydraulics for off-road vehicles.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
