Leak Detection

nVent TRACETEK  sensor cables for acids and aqueous chemicals are targeted at hazardous fluid stored in tanks and transported through systems of pipes and valves. Our cables can detect the presence of water-based solutions containing corrosive or toxic chemicals. Applications include water treatment, waste water, and chemical delivery systems for semiconductor manufacturing and pharmaceutical production. Lab drains, ground water remediation, waste acid transfer and similar fluids that are transported in double wall pipe are also good applications for our general purpose aqueous chemical sensors.

Chemical Leak Detection System

Chemical-Leak-Detection-Industrial.jpgnVent Thermal Management provides acid specific cables that are designed to react to strong sulfuric or nitric acid while ignoring rain, snow melt run off, fog and sea spray and even diluted acid mist. This means that the TT7000-HUV acid specific sensor cable can be installed out doors and exposed to various weather conditions without generation of a false alarm. Yet, should strong acid leak from a pipe or fitting, the leak is detected rapidly and the location is reported to the control panel with pinpoint location accuracy.

The TRACETEK chemical leak detection system has these basic parts:

  • Sensing cables and probes – these cables and probes directly detect and accurately pinpoint the source of the leak. They include cables used for below raised floors, drip trays overhead piping, flat probes for sumps or damp areas, and miniature probes for tight areas.
  • Leader and/or jumper cables  – these are cables that connect  the module to the sensing cable/components
  • End termination – this is the end termination on every leg of the sensing cable in the circuit
  • Accessories — the items, such as hold-down clips, that are used to secure the sensing cable in place
  • Sensor Interface Modules – these modules provide the excitation voltage necessary to operate the cable or probes. The SIM then monitors analog current and voltage levels to determine when and where a leak has occurred. The measurements are digitized and transmitted back to the control and alarm panel for user display or interface to higher level systems. These modules can be either a nonlocating alarm module for small area coverage, or an alarm and locating module that can monitor one or more large areas.
