Submersible Pressure Transducer for Tank Fluid Level Monitoring

Monitoring the level of liquid can be accomplished through the use of a pressure transducer. The density of the liquid and its height create pressure on the diaphragm of the pressure transducer to generate an accurate and cost-effective level measurement. Generally, pressure transducers can be used for level measurement from 10 inches of water column up to 10,000 PSI (700 bar).

Embedded Servo Drive Boosts Speed of Packaging Lines

Pfankuch Machinery, based in Ahrensburg, Germany, is a leading manufacturer of friction feeder systems for inserting leaflets and products into sales packaging. An embedded smart servo drive from Metronix (part of the Apex Tool Group in Sparks, MD) has allowed Pfankuch to increase the speed of its latest friction feeder — the SmartFeeder — by 50% while also doubling the positioning accuracy. This offers a massive gain in productivity for the many users of this type of packaging equipment in markets including pharmaceutical, and food and beverage processing. At the same time, the new embedded drive minimizes the hardware costs of the upgrade for Pfankuch, because the drive was adapted for the application, providing a stripped-down product suitable for OEM integration that eliminates numerous expensive components.

Custom Drive System Helps Mercedes-Benz Reduce Draft in Convertibles

The AIRCAP® automatic draft stop, offered in the Mercedes-Benz E-Class convertibles, is distinctively different from conventional angular wind deflectors. It is entirely embedded into the car body and completely concealed into the windshield frame when deactivated. In its activated state, an aerodynamically shaped wind deflector extends on top of the windshield without disfiguring the automobile’s aesthetic side line.

Gait Analysis Based on Inertial and Magnetic Sensors

Motion analysis often is based on stereophotogrammetry, which estimates the three-dimensional coordinates of points on an object by measurements made in two or more photographic images taken from different positions. While it provides very useful and detailed information about walking, the technique’s full capability of quantitative analysis of movement often is not used.
