R TraceTek Leak Detection Product Selection Guide for Water

RTraceTek Leak DetectionProduct Selection Guide for Industrialand Environmental ApplicationsScope of This GuideThis guide will help you select TraceTekleak detection products for industrial andenvironmental applications. It coverssensing cables for a variety of liquids:• aqueous solutions• liquid fuels and oils• organic solventsThis guide includes products for applications(such as double-contained piping) thatrequire special fittings and installation tools.The product information complementsTraceTek application guides, which providedesign information specific to an application.For water sensing applications in commercialbuildings, refer to Selection GuideH53874. You may obtain other Raychemliterature from our Fax-on-Demand serviceat (800) 329-4494.I. Types of SystemsTraceTek leak detection is based on asimple operating principle, which makesseveral different types of systems possible.Modular DesignTraceTek leak detection is a versatilemodular system, with interchangeablecomponents that can be configured inmany different ways.TraceTek cables are available in standardlengths that plug together with no specialtools, making them easy to install. Cable isalso available in bulk for installation indouble containment piping, with kits (soldseparately) to install connectors on thecable at access points.The range of TraceTek alarm modules andmodular components allows you to tailorthe monitoring approach and layout to theapplication. The modular system designalso makes it easy to add to or modify thelayout in the future.The different types of TraceTek alarmmodules all trigger an alarm if liquid contactssensing cable connected to the module.Contents of This GuideThis guide is divided into five sections.I. Types of Systems profiles the types ofTraceTek monitoring systems available.II. Determining the Monitoring Approachreviews key considerations when definingthe scope of leak detection, and helpsyou decide on a monitoring approach tofit your application.III. Elements of a TraceTek System describesthe basic elements of a TraceTek leakdetection system and shows typicalsystem configurations.IV. Defining a Complete System outlines thesteps to lay out a complete TraceTekleak detection system.V. Product Listings shows the leak detectionproducts available and providestechnical and ordering information.However, each type of system hascharacteristics advantageous for differentapplications and layouts.Locating System- Can monitor one or more large areas orlengths.- Indicates leak location with its digitaldisplay; pinpoints the distance, not justthe area.- Is extremely useful for concealed or inaccessibleareas, such as double-containedpipes, covered trenches, and subfloors.- Integrates separate equipment or areasinto a single sensing circuit, thus reducingfield-wiring costs significantly.Virtually no limit to the amountof non-sensing jumper cable.Can have branchesupon branches, limitedonly by length of sensing circuit.All systems may use multiple types ofsensing cable in a single sensing circuit.Up to 5000 ft (1500 m) of sensingcable per locating module.Multiple-Channel Alarm System- Independently monitors as many as12 discrete channels; displays status ofeach channel separately.- Identifies any channel with a leak, butdoes not indicate distance to the leak.- Uses common alarm and relay contactsfor all channels.- Is well suited to tank and sumpapplications.Virtually no limit to the amountof non-sensing jumper cable.Separate wiringfor each channel.Up to 100 ft (30 m) of sensing cable per channel.Single-Channel Alarm System- Provides coverage for single small areas.- Is cost-effective for small installations.- Provides an independent system for aseparate area or operation.- Is useful for separate alarm annunciationor direct equipment control.Virtually no limit to the amountof non-sensing jumper cable.Up to 100 ft (30 m) of sensing cable.Drawingsnot to scale.1
