‘switchout’

Data Acquisition using GSM/GPRS‘Wire-less’ TechnologyDrallim have recently introduced a GSM/GPRS based ‘wire-free’ solution to complementtheir range of remote monitoring field-based equipment. Wireless communications isnow a very cost effective alternative to traditional copper-wire telephony. The mobilecellular phone network is a worldwide standard operating in more than 170 countriessupporting voice, text messaging and data communications. This allows users the abilityto monitor remote operating conditions on a global scale. Drallim’s GSM/GPRS systemnamed DART has been engineered to withstand extremely hostile physical and electricalenvironments and can be easily installed anywhere. The self-contained controlequipment is able to interface with a wide range of sensor types and can also beintegrated with Drallim’s existing long distance two-wire digital multi-drop dataacquisition protocol, to provide a complete data acquisition and alarm solution for anyasset management application.System FeaturesDurable Stainless Steel Housing.Modular design and connectivity (using Quick-connect IP68 couplings).Environmentally protected against moisture to IP68 to submersion depth of 2 Metres, (testedto submersion depths up to 5 metres).Resistant to effects of dielectric cable fluids.Surface or underground site installations, (subject to signal strength).Communicates with locally installed sensor devices up to 10 metres rangeBattery powered, with remote ‘low battery’ alarm indication, (Lithium battery life of up to 3years, with optional replacement battery packs).Power adaptor for use where other power sources or renewable sources can be used.Case Standard studies GPRS and / GSM independent DART Controller reports can are accommodate available on up request. to 10 individual mixed typemeasurement sensors per unit, using Localised Power Source.All equipmentis backward-compatible with the existing generation of Drallim RDT’sPortable device reader available.Fully programmable, remotely or locally.Detachable antenna for location above or below ground, for optimum signal transmission.Can accommodate multi-sensor digital devices, (Adaptable for analogue types).User definable periodic bulk data transfer, up to 36 hours, (based on scan rate interval of 5minutes) ensuring optimal economic data transmission-operating costs.Alarm conditions routed to server and SMS Messaging upon poll cycles.Transfer-poll interval in the range: 1 minute to 1 hour, with typical transducers poll rate of 5minutes for a 5-year battery lifetime.

A Remote Monitoring System that provides fast, convenient access, toautomatically acquire, record and view system events, to meet challengingoperational and asset management needs.NotesWebsite: www.drallim.comContact UsIf you would like further information or support on any aspect of thispublication, or would like to discuss your remote monitoring needs personally,please contact:Drallim Industries Ltd.Millwood House,Drury Lane,Ponswood Industrial Estate,St. Leonards-on-Sea.East Sussex.TN38 9BAEngland.Phone: +44 (0)1424 205140Fax: +44 (0)1424 202140E-Mail: sales@drallim.comwww.drallim.com
