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
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
