AI Technical Summary
The wire connection method of traditional water immersion level sensors is prone to causing the waterproof sealant to loosen due to bending, resulting in water leakage gaps and causing the water immersion sensor to fail.
The design employs a sleeve, reed switch, float ring, and dual-core wire. It is fixed and installed using clamping sleeves and connecting sleeves, and sealed with a waterproof adhesive layer to prevent wire movement. Combined with a scraper structure, it facilitates maintenance and improves sealing and reliability.
This effectively avoids relative movement between the wires and the waterproof adhesive layer, improves the sealing and functional reliability of the water immersion sensor, prevents the formation of leaks, and ensures the stable operation of the sensor.
