The SN-3002-SJ-N01 King Shell water immersion sensor is engineered for critical leak detection in industrial, commercial, and infrastructure applications. It employs an AC-based sensing principle, which applies an alternating current to the detection electrode, effectively mitigating galvanic corrosion and oxidation to ensure consistent performance and a long operational lifespan even in continuous immersion scenarios.
This sensor delivers two distinct output signals for maximum integration flexibility. The RS485 interface communicates via the Modbus-RTU protocol, allowing for direct digital connection to supervisory control and data acquisition (SCADA) systems, programmable logic controllers (PLCs), and data loggers. Simultaneously, the integrated dry-contact relay provides a simple, voltage-free switch closure for audible alarms, indicator lights, or direct input to legacy control systems. Its robust housing and electrical design support operation in a wide temperature range and varying water qualities.
