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
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
