Product Specifications

Technical details and manufacturing context for Fluid Level Sensor

Definition
A component integrated into reservoir systems that monitors fluid levels to ensure proper operation, prevent overflow or dry running, and provide data for process control and automation.
Working Principle
Operates by detecting changes in physical properties (such as pressure, capacitance, conductivity, or ultrasonic reflection) caused by the presence or absence of fluid at specific points within the reservoir, converting these changes into electrical signals for measurement and control.
Common Materials
Stainless Steel, Plastic, Electronic Components
Technical Parameters
  • Measurement range and accuracy for fluid level detection (mm) Customizable
Components / BOM
  • Probe/Sensing Element
    Directly interacts with the fluid to detect level changes
    Material: Stainless Steel
  • Signal Transmitter
    Converts physical detection into electrical signals
    Material: Electronic Components
  • Housing
    Protects internal components from environmental factors and fluid exposure
    Material: Plastic or Stainless Steel
Engineering Reasoning
0-100 kPa differential pressure, -40°C to 125°C ambient temperature
150 kPa overpressure, 140°C internal temperature, 95% relative humidity continuous exposure
Design Rationale: Diaphragm plastic deformation at 150 kPa exceeding 0.2% yield strain, dielectric breakdown at 140°C exceeding 150°C glass transition temperature of polyimide insulation
Risk Mitigation (FMEA)
Trigger Capacitance plate contamination by conductive fluid particles exceeding 5μm diameter
Mode: Capacitance measurement drift beyond ±0.5% FS accuracy
Strategy: Hermetic sealing with 0.1μm PTFE membrane and redundant optical backup sensor
Trigger Thermal cycling between -40°C and 125°C at 10°C/minute rate
Mode: Solder joint fatigue cracking after 5000 cycles
Strategy: Conformal coating with 0.5mm silicone gel and strain-relief mounting
