Water Leak Detection Sensor

FD-100

Category: Sensors

E4A's water leak detection sensor delivers reliable, Bluetooth® 5 enabled water leak detection for industrial environments where early awareness is critical. Featuring a rugged wall-mounted unit paired with a floor-level sensor, it provides accurate monitoring of leaks, drips, and pit overflows exactly where they occur. Its wireless Bluetooth® 5 connectivity ensures instant alerts to personnel and seamless reporting to a central gateway, enabling rapid response and facility-wide visibility. Designed for harsh, high-risk locations, the FD-100 sensor offers a simple, durable, and cost-effective solution to prevent equipment damage, reduce downtime, and maintain operational safety across industrial sites.

Early Leak Detection

Monitors drips, pipe leaks, and pit overflows, providing instant awareness before water causes equipment damage or operational disruption.

Simple Installation

Mounts quickly on any wall with flexible cabling to the floor sensor, enabling deplyoment in restricted, hard-to-reach, or retrofit locations without extensive modifications.

Downtime Reduction

Detects issues early, helping prevent unplanned shutdowns and minimizing production interrupitions, keeping critical operations runnning smoothly.

Centralized Reporting

Seamlessly integrates with a central gateway to provide facility-wide monitoring, historical tracking, and actionable insights for operational planning.

Industrial-Grade Durability

Constructed to withstand industrial environments, including factories, mechanical rooms, and high-risk zones with dust, moisture, and temperature changes.
