LT460S Liebert Sensor

LT460S Liebert Sensor Datasheet

The zone leak detection sensor modules install quickly and work simply for reliable warning of potentially hazardous moisture conditions. The supervised zone leak detector uses up to 100 feet of flexible Liebert® moisture sensing cable, offering protection from unwanted leaks.

Overview

The Liebert LT460S Liqui-tect sensor provides reliable zone detection of leaks by constantly monitoring for the presence of water or other conductive liquids. Designed for critical infrastructure like data centers and network closets, this module offers a versatile solution for perimeter sensing or serpentine coverage. It is engineered to monitor up to 100 feet of flexible moisture-sensing cable, providing early warning of potentially hazardous conditions to protect sensitive electronics and equipment. The unit features a durable metal enclosure with a hinged top door for easy access to internal components and status LEDs for visual indication of system normal, alarm pending, and leak detected states.
