Beijing Subway Construction Adopting Helicomm Wireless Networking Technology to Improve Safety and Monitor Sensors

Beijing Metro Subway recently adopted Helicomm's ZigBee wireless technology to improve their workers safety and to monitor the dust sensors for Subway Line 4. Beijing Subway has 9 lines, and Line 4, completed in September 28, 2009, is the newest of the lines. It is 28.2 km long with 24 stations. Helicomm's wireless mesh networking technology enables the Subway Tunnel Safety Warning System, which consists of wireless readers, wireless identification tags, and the wireless dust sensors. The success of this project opens up new application opportunities for Helicomm's  wireless networking technology for Metro Subway safety and construction application. China plans to build 79 subway lines in 22 cities across the country by 2015.

The system in the future will incorporate more sensors to improve the monitoring capabilities of tunnel construction. These sensors include stress sensors, strain sensors, and sensors used for the geographical prediction system. "Helicomm's wireless networking technology has been widely deployed in applications which require reliable communication and ease of deployment. "The success of this subway construction project is another good example of how our technology can be used in various sensing and monitoring applications," says C.C. Huang, Helicomm CTO.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
