Description of TraceTek Leak Detection System
TRACETEK SENSING CABLES
The TraceTek leak detection system is based on sensing cables that detect liquid at any
point along their length. Four types of TraceTek sensing cables are available to detect
different types of liquids. While multiple types of sensing cables may be used in a single
sensing circuit, if different types of fluid are being monitored in the same area it may be
more effective to create multiple circuits, each with dedicated sensor cable of a specific
type.
COMPONENTS OF TRACETEK LOCATING SYSTEM
TraceTek leak detection is a versatile modular system, with interchangeable components
that can be configured in many different ways. For more information on the products and
systems available, consult the appropriate TraceTek product selection guide: Raychem
document H53874 for water detection in commercial buildings, H55869 for industrial and
environmental applications.
A TraceTek locating system provides distributed leak detection and location over long
distances and wide areas. A TraceTek locating circuit consists of a TraceTek locating
module (TTDM-128, TTSIM), sensing cable and/or point sensors, and circuit components
(leader cable, jumper cables, end terminations, weighted lengths, and branching
connectors) with connectors that allow components of the system to plug together.
The weighted length resistor simulates a 15-ft (5-m) length of sensing cable. Installed at
the boundary between two areas of sensing cable, the weighted length allows the user to
clearly identify the area where a leak has occurred.
The branching connector enables the sensing cable to be branched. An end
termination
completes each branch. At the branching connector, the system first counts
the sensing cable along the branch (middle connector) to its end termination, before it
continues with the main run. Two built-in 15-ft (5-m) weighted-length resistors allow the
