The LD Series are Plastic Leak Detection Sensors designed for impeccable performance in detecting conductive liquids. Employing a solid-state relay pulse alarm mechanism, these sensors ensure reliable detection and notification of disruptive liquid leaks.

Perfect for Aggressive and Corrosive Chemicals
Suitable for a diverse array of applications, these detectors are ideal for use in environments involving exposure to chemicals, acids, and bases. This includes areas like tank or sump leaks, industrial process piping, dosing pump skids, and double-walled tanks. Note that these sensors only work on electricly conductive liquids. 

Small Size and Design
This sensor features an ultra-low-profile footprint, about the size of a U.S. quarter, making it easy to fit into tight spaces or under equipment where leaks are most likely to occur. Its compact design minimizes interference with foot traffic or maintenance while still providing full-scale leak detection performance



Capacitive Fail Safe Operation
The LD Series uses a capacitive sensing method to reliably detect conductive liquids even in harsh industrial environments. This fail-safe design ensures the sensor continuously monitors for leaks and triggers an alarm instantly, reducing downtime and protecting valuable equipmentVisual and

Audible Alert System
The LD Series is equipped with red LED indicators for alarm conditions and green LEDs to indicate power status. This dual-indication system ensures that any disturbance is promptly and clearly signaled to maintenance personnel.

Adjustable Sensitivity Setting
The LD Series includes an adjustable sensitivity feature that allows you to fine-tune detection levels for your specific application. This flexibility ensures accurate leak detection across a range of liquids and environments, minimizing false alarms and improving system reliability.

NPN | PNP Pulse Relay Output
Equipped with both NPN and PNP pulse relay outputs, the LD Series integrates easily with existing control systems. This versatile output configuration allows for seamless alarm triggering and system automation, giving you more control over your leak detection response.
