Teren WLD311 – Water Leak Detector with Remote Electrode

Reliable Protection Against Water Damage & Overflow

The Teren WLD311 is a robust water leak detector designed to provide early warning of leakage or immersion in critical industrial and commercial environments. Utilizing the conductive principle of water, this unit offers rapid detection with a response time of less than 2 seconds, helping you prevent costly damage to equipment and infrastructure.

This specific model features a remote sensing electrode connected via cable, making it the ideal solution for monitoring hard-to-reach areas, drip pans, or specific points within a facility. Beyond leak detection, the WLD311 is versatile enough to function as a floatless (conductive) level switch, offering reliable control for tanks and reservoirs.

Key Features & Benefits

• Remote Sensing Precision: Supplied with a cable-connected sensing electrode, the WLD311 allows you to place the detection point exactly where it is needed—under floors, inside equipment cabinets, or in water tanks—while mounting the main unit in a convenient, accessible location.

• Dual Alert System: The unit ensures you never miss an alarm status with a built-in audible buzzer and a high-visibility LED indicator (Green for normal, Red for alarm).

• Customizable Operation: Need silent operation? The internal buzzer can be easily disabled via a DIP switch, allowing the unit to adapt to noise-sensitive environments.

• Robust Industrial Design: Housed in a fire-retardant ABS+PC enclosure with an IP65 protection rating, the WLD311 is built to withstand dust and moisture in harsh industrial settings.

• Seamless Integration: Features a Single NO (Normally Open) SPST relay output, allowing for easy integration with Building Management Systems (BMS), PLCs, or external alarm panels to trigger shut-off valves or remote alerts.

• Safe & Stable: The power supply, electrode, and output relay are electrically isolated, providing strong anti-interference ability and protection against overvoltage and reverse connection.
