The SN‑3002‑SJ‑N01 King shell water immersion sensor (RS‑485) is an industrial-grade alarm detector designed for reliable leak detection in harsh environments. Powered via DC 10–30 V, it uses AC detection technology to mitigate oxidation on its electrode, ensuring long-term responsiveness. It provides dual outputs: an RS‑485 Modbus‑RTU interface for digital integration into SCADA or PLC systems, and a dry-contact relay for straightforward signaling. Its detection capability extends up to 30 m with an optional cable, perfect for shielding critical equipment or infrastructure. Operating across –20 °C to +60 °C with 0–80 % RH, and tolerating tap and pure water, the unit supports robust, maintenance-free performance. Compact yet durable, it delivers efficient water immersion alerts in industrial, environmental, and commercial applications.
Features:
- Utilizes AC detection to prevent electrode oxidation
- Dual output: RS‑485 Modbus‑RTU & dry-contact relay
- Supports optional 30 m external detection cable
- Wide supply range: DC 10–30 V
- Rugged build—works in drifts from tap and pure water
- Operates in –20 °C to +60 °C, max 80 % RH
