GS-LDA-2
Water Leak Detection System
The
GS-LDA-2
Sensor Interface Module monitors up to 1500 meters of GuardSen sensing cable (GS-LDC-2). When liquid is detected, the GS-LDA-2 unit indicates the leak, displays the location of the leak and switches a relay to provide local voltage-free contact closure.
The GS-LDA-2 can be used as standalone leak detection alarm unit or can also communicate to a host monitoring system such as PLC or other monitoring systems by using standard RS-485 protocols.
The low cost of the GS-LDA-2 makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required.
DESIGN FEATURES

- 12Vdc power supply
- Each GS-LDA-2 unit has a unique address assigned with software – no switches
- Built-in buzzer (85dB)
- DIN rail mounted for easy installation
