Provides microprocessor reliability in a compact design
For use in a variety of liquids, including foods, beverages, chemicals, oils, water, as well as slurries and some solids, Madison Co. has added the U3M Ultrasonic "Mini Probe" to its full range of ultrasonic level sensors. The U3M has a compact design that extends just over 2 inches in height above the tank or drum surface and has an operating range of 4 inches to 6 ft. The U3M has a PVC housing that allows for an operating temperature range of -40 to 60C that can be increased to as high as 125C with an optional CPVC or Kynar housing. The U3M's microprocessor-based circuits provide a temperature-compensated signal for improved accuracy and the ability to filter false echoes produced by peripheral obstructions. On-board push buttons allow for calibration without the need for software and computers. Optional RS485 communications are available for computer interfacing and for networking up to 128 sensors. The "Mini Probe" has a self-cleaning sensor face and will automatically adjust power and sensitivity to any environment. Madison Co. http://rbi.ims.ca/4912-535
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
