FLUID POWER: Bray Controls has expanded and improved its Series 52 2N1 ProxSensor line of valve status monitors to now include AS-I, DeviceNetTM and PROFIBUS® DP BUS network units with a solenoid drive, plus many other new features. Bray’s 2N1 ProxSensors combine two proximity sensors in one compact, self-contained and fully sealed enclosure. These valve status monitors deliver the rapid, bounce-free electronic valve signaling required for PLC, computer and solid-state circuitry used in process control and information networks. All units have a five-year warranty against material or workmanship defects. Bray’s new BUS Intelligent 2N1 ProxSensors offer all the features of the dc and ac units, plus network protocol/communication and remote access to valve position and diagnostics. These units contain two BUS-powered proximity sensors and applicable network pin and solenoid drive connections. The Series 52 is engineered to be impervious to vibration, moisture and most chemical and corrosive agents since all internal components are completely encapsulated with epoxy resin inside the rigid, fully sealed polymer enclosure. Multi-pin electrical connectors are weatherproof and provide quick-connect installation. Standardized factory pre-wiring prevents field wiring errors. The 2N1 ProxSensor mounts directly to Bray pneumatic actuators, eliminating contamination buildup between sensor and actuator.
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.
