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
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
