RKC's LT1 is a back-pressure level switch for upper/lower limit liquid sensing. There are no moving mechanical parts, just a back-pressure sensor and built-in orifice to supply gas. A single tube handles liquid level alarm and sensing. The LE100/110 high-accuracy linear meter series can measure liquid levels in single and multiple chemical baths or as a pressure sensor. The built-in back-pressure sensor in the 1/16th DIN microprocessor can measure levels up to 1,000 mm. The front panel display has two digital readings for actual level and set value, up to eight level set points, and four push buttons for setting the unit. A single-touch setup can do empty adjustment, span adjustment, and automatic specific gravity computation, and a built-in linearizer compensates for variations in tank shapes. The meters display units such as millimeters, percent, liters, and milliliters. They have a repeatability of ± 0.3 percent of full span, and a 0.2-second sampling time.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
