جهاز يكشف تسرب المياة و السوائل في الانابيب و يحدد موقع التسرب. جهاز للاستخدامات الصناعية Theory of Operation PAL-AT uses a pulsed cable-radar technology to detect leaks. PAL-AT sends out low voltage pulses on a cable and monitors reflections received back at the panel. PAL-AT electronically divides the cable into short increments and measures the reflections from each increment. memory during the reference procedure in a permanent record called the "master" map. When stores the measured values mode, PAL-AT compares the current condition with the master map. Significant changes from the master, monitor for instance when the cable gets wet, cause PAL-AT to enter the alarm mode. This latest generation of PAL-AT systems automatically creates a new master map after a leak event is detected. This puts the system back on-line immediately to monitor the entire cable for leaks getting largera or new leaks
