Product Specifications

Technical details and manufacturing context for Leak Sensor

Definition
A critical component within a Leak Detection System that monitors for liquid leaks in pipelines, tanks, or equipment, typically using electrical or optical methods to identify fluid presence and trigger alarms or automated responses to prevent damage, contamination, or safety hazards.
Working Principle
Operates by detecting changes in electrical conductivity, capacitance, or optical properties when liquid comes into contact with sensor probes, converting this physical change into an electrical signal that is transmitted to the control system.
Common Materials
Stainless Steel, Polymer Housing, Copper Electrodes
Technical Parameters
  • Sensor probe spacing and dimensions (mm) Standard Spec
Components / BOM
  • Detection Probes
    Direct contact with liquid for conductivity/capacitance measurement
    Material: stainless steel
  • Signal Processor
    Converts physical detection into electrical output signal
    Material: electronic components
  • Protective Housing
    Shields internal components from environmental factors
    Material: corrosion-resistant polymer
Engineering Reasoning
0.1-10 bar (1-1000 kPa) differential pressure
15 bar (1500 kPa) burst pressure or -0.2 bar (-20 kPa) vacuum collapse
Design Rationale: Diaphragm rupture due to yield strength exceedance (316L stainless steel: 290 MPa yield strength) or capacitive sensor dielectric breakdown (air: 3 MV/m dielectric strength)
Risk Mitigation (FMEA)
Trigger Electrolytic corrosion from chloride ion contamination (>25 ppm Cl-)
Mode: Sensor membrane perforation causing false negative readings
Strategy: PTFE-coated sensing elements with hermetic sealing (IP68 rating)
Trigger Capacitance drift from dielectric constant change (εr water=80 vs εr air=1)
Mode: Calibration offset exceeding ±2% FS accuracy specification
Strategy: Temperature-compensated ASIC with 24-bit ADC and automatic baseline correction
