Wireless sensors for industrial AutomationAt the Hanover Fair, in addition to electromechanical wireless switchgear working according to the 'energy harvesting' principle, Steute will be introducing a new generation of wireless sensors using the sWave wireless protocol, running on the 868 / 915 MHz frequency band.
The RF RC 10, housed in a compact, square, thermoplastic enclosure, can be flexibly integrated in machine construction. It is equipped with reed contacts, while the cylindrical wireless sensors RF GS M25 and RF GS M30 detect the target by the GMR effect. This offers the advantage for users that the sensor can also be mounted on vibrating machines and plants because vibrations cannot influence the GMR effect. Thus the application field for magnetic sensors has been extended.
The multi-network capability of the sWave wireless technology permits use of several sensors within one transmission area. Bi-directional signal transmission is one of the specialities of the wireless protocol: with an in-built time delay, acknowledgement is sent of each transmission confirmation.
The sensors have a calculated life of more than one million operations and a switching frequency of max. 12,000 telegrams (incl. repetitions) per hour. They are available for transmission ranges 868 MHz (Europe & Asia) and 915 MHz (America) and can thus be applied worldwide.
For all three sensors, power is supplied by a long-life lithium battery that lasts for several years thanks to the extremely low energy consumption of the sWave wireless protocol.
The wireless sensors have been designed for reliable position detection without wiring or pipe laying and for application in an industrial environment. Because no wires are required, Steute offers electrical engineers the chance to apply non-contact sensors more flexibly than before. Thus the sensors are optimally suited to integration in plants designed on the basis of 'Industry 4.0' and 'Smart Factory' and are characterised by decentralised intelligence and increased flexibility.
The Steute range is distributed in the UK by forTop Automation and Energy Control.
