Unlike traditional slip-ring transducers, the TorqSense sensors provide a simple non-contact technology for measuring the power in drive shafts and other rotating elements. Torsion is sensed by a pair of SAW strain gauges bonded to a shaft at right-angles to each other. One senses compression and the other tension, and this information is transmitted via a radio frequency couple to the decoding electronics which generates outputs for torque, speed, power and angle.

The National Institute of Standards and Technology released this week its guidelines describing the various risks to data security and personal privacy that RFID deployments may pose...

The sensors are supplied with a steel protective tube and an interchangeable ceramic inner tube and are used to monitor temperatures of around 1200° - 1300° C in two boilers as part of a new flux firing system. They conform to standard class 2 according to IEC 584 thermocouple type N. The sensor is mounted through the top of the furnace to a depth of approximately 700 mm.

Zlinx solutions operate within the ISM and 2.4 GHz frequencies. Coupled with extraordinary receiver sensitivity, this radio modem can full-duplex over long distances and through the most difficult environments. Special filtering technology blocks cell phone, pager and other wireless interference. The modem can operate from 9600 bps to 115.2kbps and transfers RS-232/422/485 serial signals. Its over-the-air data rate is 115kbps.

The BOS 6K is designed using the autocollimation principle. This means the emitter and receiver are on the same optical axis, ensuring a high degree of switching accuracy. A built-in polarizing filter suppresses interference such as reflections, thus increasing process reliability. The sensor's pulsed, visible red light increases ambient light rejection and makes setup and adjustment a snap.

The UNO-3072 can withstand high temperatures and vibrating environments to fulfill tough requirements. Lastly, it’s an open platform which can fulfill demanding requirements from the field and is an ideal solution for any industrial automation or control task.

USB Industry Orders Caution

Setting a new industry standard for performance, reliability and value, the FL4000 Flame Detector gives process and plant engineers a powerful new tool in protecting people, equipment and facilities from dangerous hydrocarbon flame sources. It provides exceptional performance and reliability while minimizing operational costs associated with false alarms.

Demand for instant access to physical data is becoming essential to people's everyday lives and the need for easy to use wireless sensor network (WSN) technology is greater than ever. WSNs are currently being deployed into a wide array of applications in the agriculture/environmental, healthcare, defense, transportation, supply-chain logistics, and industrial automation markets.
