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® 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.

Asset Protection

Monitors drips, leaks, and pit overflows, providing instant awareness before water causes damage

Labor Savings

Eliminate routine manual facility leak inspections with
automated, continuous leak monitoring

Downtime Reduction

Minimize operational disruptions by addressing issues before they lead to system failures or shutdowns

Flexible Deployment

Cable-free sensor unit allows flexible positioning and simple, frequent relocation as site needs change

Sensor Integrity Alert

Detects if the sensor has been moved, tilted, or flipped—
ensuring monitoring remains accurate and reliable

Industrial Durability

IP65-rated housing provides strong protection from dust and water, making it ideal for demanding industrial sites
