Isolated Water Flood Transmitter Key benefits Detects water quickly and reliably by sensing the change in electrode impedance when water appears, enabling fast response to leaks and flooding. Fully isolated inputs and outputs prevent interference and protect connected control systems, reducing false alarms and equipment risk. Sealed plastic housing and sensitivity electronics provide durable, lowmaintenance operation in indoor environments where floorlevel water detection is required. What it does (function) Detection principle: sensing electrode array detects impedance change when immersed in water. The signal is amplified, shaped and compared by a dedicated integrated chip to generate a clear water/nowater output. Output options: provides drycontact or /low level logic changes to indicate water presence. Relay output mode is available for direct connection to alarm panels or control systems. Optional auxiliary electrode: an additional electrode can be added to extend the detection range or coverage area. Design and materials Integrated, fully sealed plastic housing for protection against dust and moisture, suitable for floor or lowlevel mounting. Main electrode includes an isolation layer; the transmitter uses photoelectric isolation and transformer isolation to separate sensing circuitry from power and outputs. Power input and alarm outputs are fully isolated from the sensing element to improve safety and compatibility with sensitive equipment. Compatibility and performance Compatible with standard alarm panels, building management systems, and monitoring equipment that accept dry contacts, digital /low logic inputs, or relay signals. sensitivity with reduced false alarm rate due to dedicated signal processing. Reliable isolation and sealed construction make it suitable for environments where electrical isolation and longterm stability are required. Typical applications (practical scenarios) Server rooms and data centers: floorlevel leak detection under racks and cable trays to trigger alarms or automatic shutdowns before equipment is damaged. Telecom sites and base stations: continuous monitoring of indoor equipment rooms to detect condensation or water ingress and protect critical communications gear. Archives, libraries and museums: early detection of floor leaks in storage or display areas to protect sensitive documents, books and artifacts. Installation notes Designed for easy integration with existing alarm or monitoring systems; select the appropriate output mode (dry contact, logic level, or relay) based on your control interface. Use the optional auxiliary electrode if a wider detection area is required; follow standard wiring and mounting practices to maintain the housing seal and isolation integrity. Features summary Isolated water sensing via impedance change Dedicated integrated chip for amplification, shaping and comparison Dry contact, /low logic or relay output modes Optional auxiliary electrode to extend coverage Photoelectric and transformer isolation; fully isolated power and outputs Fully sealed plastic housing; sensitivity and low false alarms For applications requiring reliable floorlevel water detection with electrical isolation and flexible outputs, this isolated water flood transmitter provides a practical, lowmaintenance solution.
