Product Introduction
The GLD3200 liquid leakage sensor can monitor the leakage situation in the environment in real time. At the same time, it has the function of detecting broken cables and triggering an alarm. Once a leakage or a broken cable is detected, the controller will issue an alarm and transmit the leakage information through the RS485 communication interface. It will also activate a relay to output a switching signal. This leakage controller has been programmed according to the MODBUS-RTU protocol, which is convenient for integration with the monitoring system and can monitor up to 500 meters of sensing cables.










Product Parameters
The power supply of the GLD3200 liquid leakage controller is 12-24VDC wide voltage supply. It has one relay output. It can connect to RS485 (MODBUS-RTU protocol). It can monitor up to 500 meters of leakage detection cables. Once a leakage is detected, its response time is less than 3 seconds. It is installed in a 35mm rail mounting method, which can be flexibly installed in the cabinet.
Product Certification
The GLD3200 Liquid Leak Controller has obtained certifications such as CE, ROHS, FCC, and those from the metrology institute.
Typical Application Industries of the Product
It is applicable to liquid leakage detection in fields such as data centers, semiconductors, new energy, photovoltaic power, petroleum and petrochemicals, and power environment systems. It not only can detect water, but also can detect leaks of various acidic and alkaline liquids.

Can be Used in Conjunction with Detection Cables
The GLD3200 liquid leakage controller can be used in conjunction with GDL2 detection cables, GDL3 leakage detection strips, GDL2M water detection cables, GDL4S, GDL7S acid-base leakage detection cables, and GDL4Y fuel leakage detection cables, etc.
