Addressable Water Leak Sensing Cable for Data Center & Critical Infrastructure Detection

ProEngiTools / Sensing Systems Engineering & Technical Overview

The LOC-1000 Series Addressable Water Sensing Cable is engineered to provide continuous, high-sensitivity liquid leakage detection and precise pinpoint locating along entire cable runs. Designed specifically for mission-critical facilities—including hyperscale data centers, server equipment rooms, semiconductor cleanrooms, pharmaceutical labs, and commercial high-rise mechanical rooms—the sensing cable detects the presence of conductive fluids (tap water, chilled water, condensation, and mild chemical solutions) at any point along its length.

Unlike conventional parallel-wire detection cables susceptible to mechanical stress, memory coil deformities, and electromagnetic interference (EMI) from adjacent high-voltage power feeds, the LOC-1000 utilizes an advanced helical winding geometry. Two conductive fluoropolymer-coated sensing conductors and two insulated low-resistance signal carrier wires are precision-twisted around an ultra-flexible core. This spiral design provides superior structural elasticity, cancels ambient electrical noise, significantly reduces nuisance false alarms, and delivers over 65 cycles of abrasion resistance.

Operation is governed by precision loop resistance measurement: when liquid bridges the outer conductive fluoropolymer sensing cores, conductive contact creates an electrical loop, altering loop current proportional to the distance from the controller. The connected locating monitoring module instantly calculates the exact meter mark of the leak, displaying the precise location on the BMS interface or local touchscreen.

The cable features an automatic self-recovering architecture. Once the detected water source is removed and the cable is dried or wiped down, electrical loop resistance restores to baseline immediately, allowing the cable to be reused repeatedly without component degradation or replacement. Pre-installed industrial waterproof modular male/female twist-lock connectors enable rapid tool-free daisy-chain expansion up to 1,500 meters per monitoring zone.
