Overview
The National Instruments wireless sensor network (WSN) platform delivers low-power measurement nodes that offer industrial certifications, reliable networking, and optional weatherproof outdoor enclosures for long-term, remote monitoring applications. The measurement nodes have direct sensor connectivity and a 2.4 GHz radio to wirelessly transmit data to a WSN gateway. Each serial node features one serial port and two digital I/O channels that you can configure for input, sinking output, or sourcing output. With NI LabVIEW grpahical system design software, you can easily configure your network, collect measurement data, trigger alarms through SMS or email, and even view monitoring data within a web browser. With the NI LabVIEW Wireless Sensor Network (WSN) Module, you can customize the behavior of programmable NI WSN measurement nodes and create an autonomous interface to serial-based sensors, instruments, and control boards. Use this module to optimize node behavior for your application: customize sample and transmission rates, perform onboard analysis or data reduction, respond to digital value changes, perform local control of DIO lines, and even store data to flash memory.

◾ Programmable, autonomous interface to serial sensors, instruments, and control boards
◾ Deploy embedded code to create a local communication loop between the node and serial device
◾ Create a reliable network, with support for hundreds of nodes, to monitor your assets or environment
◾ Programmable with the LabVIEW Wireless Sensor Network (WSN) Module: Customize node behavior to extend battery life, increase sample rates, save data locally, and perform local analysis and DIO control
◾ NI-WSN software that provides easy network configuration, drag-and-drop LabVIEW programming, and support for logging, alarming, and web-based data visualization
◾ Low-power operation with up to 3-year battery life
◾ 2.4 GHz IEEE 802.15.4 radio that provides up to 300 m outdoor range
◾ 1 serial port per node with user-selectable baud rates, parity bits, stop bits, and flow control
◾ Two bidirectional digital channels configurable for input, sinking output, or sourcing output
◾ Industrial ratings: -40 to 70 °C operating temperature and 50 g shock, 5 g vibration

Surface Mount Precision Plate Resistors

High stability and low temperature coefficient are the main features of the Precision Wirewound resistors type RMB RMBS models just as maintenance parts. Their performances can be compared with those of the best film resistors but they have in addition a greater power rating. RMBS styles meet the more severe requirements of NF C 83-210 (all RMBS styles are approved) and characteristic U of MIL-R-26 E (approximate size of RW 70 and 79 resistors) specifications. The two models RMB and RMBS have a similar construction. RMBS are submitted, in addition to a process which further increases the stability. On request, non-inductive resistors are available under the reference RMB NI.

FEATURES
• 0.75 W to 3 W at 25 °C
• NF C 83-210
• CECC 40201-005
• Low temperature coefficient ≤ ± 50 ppm/°C
• Low ohmic values 15 mΩ available
• Excellent behavior against humidity
• Electrical insulation
• Mechanical strength
• Accurate sizes
• Termination = Sn/Ag/Cu or pure matte tin according to the ohmic value
