Product Specifications

Technical details and manufacturing context for Water Level Sensor

Definition
A critical component in water supply and drainage systems that monitors water levels to ensure proper system operation, prevent overflow or dry running, and provide data for automated control systems. It plays a vital role in maintaining water pressure, managing storage capacity, and triggering alarms or control actions based on preset level thresholds.
Working Principle
Operates by detecting changes in physical properties (such as pressure, capacitance, conductivity, or ultrasonic reflection) caused by water presence or level changes, converting these changes into electrical signals that can be interpreted by monitoring or control systems.
Common Materials
Stainless Steel, Plastic Housing, Electronic Components
Technical Parameters
  • Measurement range of water level detection (mm) Customizable
Components / BOM
  • Sensing Element
    Detects physical changes caused by water level variations
    Material: Stainless Steel or Ceramic
  • Signal Transmitter
    Converts detected changes into standardized electrical signals
    Material: Electronic Components
  • Protective Housing
    Protects internal components from water, corrosion, and physical damage
    Material: Stainless Steel or Plastic
Engineering Reasoning
0-10 m H₂O (0-98.1 kPa)
15 m H₂O (147.15 kPa) hydrostatic pressure
Design Rationale: Diaphragm rupture due to exceeding 316L stainless steel yield strength of 290 MPa at 0.1 mm thickness
Risk Mitigation (FMEA)
Trigger Electrolytic corrosion from 500 ppm chloride concentration in water
Mode: Sensor membrane perforation causing 100% measurement error
Strategy: Apply 50 μm PFA fluoropolymer coating with 0.01 mm/yr corrosion rate
Trigger Thermal shock from 50°C/min temperature gradient during steam cleaning
Mode: Ceramic substrate cracking at 300 μm defect propagation
Strategy: Implement 2°C/min maximum heating rate control with PT100 thermal protection
