The PAL-AT family of sensor cables are able to meet the specific requirements of a wide variety of applications and environments including subfloors, containment pipe systems, direct burial and foam insulated pipes. The sensor cables offer the leak detection designer flexibility and choice in selecting the proper cable for the desired system sensitivity.
All PAL-AT cables and connectors are easily spliced or repaired in the field to minimize downtime and repair cost.
PAL-AT AGW-Gold and AGT-Gold sensor cables have the ability to detect both water-based and hydrocarbon liquids. This reduces the number of sensor cables required in many applications.
Each of these PAL-AT sensor cables can be dried and reused after a water-based or volatile hydrocarbon leak has been cleaned up. These cables have no exposed metal and are designed for corrosive chemical applications. Each individual strand of braid wire is coated with a high-temperature, corrosion-resistant polymer and the length of the cable is covered with a fluoropolymer overbraid. Because there is no exposed metal, the Gold cables eliminate the need for special isolation precautions in cathodic-protected pipe applications.
PAL-AT TFH-Gold hydrocarbon sensor cable uses a hydrocarbon permeable core to detect hydrocarbon liquids while ignoring water-based liquids. In most cases, the sensor cable must be replaced after exposure to hydrocarbons.
TFH-Gold is a wicking cable specifically designed to detect only hydrocarbons. This cable may be direct buried in slotted PVC pipe, or screen pipe, to a maximum depth of 20 ft (6 m) to locate fuel leaks while ignoring the presence of water. This is ideal for monitoring single-wall pipes and tanks. The cable is suitable for applications where hydrogen sulfide or other corrosive gases may be encountered, such as refineries and oil fields.
Sensitivity is the length of wet cable that is required to activate the PAL-AT under standard sensitivity settings. The length required for quick-drying AGW-Gold refers to the submerged length of the cable. Wicking cables AGT-Gold and TFH-Gold will quickly draw a liquid into the cable through capillary action when it is in contact with a 1/16' (2 mm) film of liquid. The length of wet cable required for wicking cables is the saturated length of cable. For example, if a few inches of AGT-Gold cable contact a film of water at 5,000 ft (1,500 m), in less than two minutes, the cable will be saturated sufficiently and the PAL-AT will go into alarm. The PAL-AT sensitivity can be adjusted.
Sensor cable shall detect only hydrocarbons while ignoring water and water-based liquids. The cable is designed for direct burial in slotted PVC pipe, or screen pipe, to a maximum depth of 20 ft (6 m) and capable of providing a response time of not more than four minutes after contact with most hydrocarbon liquids. The sensor cable is not reusable after exposure to hydrocarbons.
