Industrial Stainless Steel Submersible Pressure Water Level Sensor 0-5m
💧 Gravity Industrial Submersible Water Level Sensor (0–5m)
🧩 Overview
Industrial-grade water level (depth) sensor
Measures liquid depth up to 5 meters
Fully submersible (IP68 waterproof)
Suitable for tanks, wells, rivers, and reservoirs
⚙️ Working Principle
Sensor is placed inside liquid (submerged)
Water pressure increases with depth
Internal pressure sensing chip detects pressure
Converts pressure → 4–20mA current signal
Depth calculated using pressure relation (ρgh)
