Product Specifications

Technical details and manufacturing context for Seal Integrity Sensor

Definition
A component integrated into sealing doors that continuously monitors the condition and effectiveness of door seals, detecting leaks, gaps, or seal degradation to ensure proper closure and environmental isolation.
Working Principle
Typically uses pressure differential, contact sensing, or optical methods to detect when a seal is compromised, sending signals to control systems when integrity falls below specified thresholds.
Common Materials
Stainless Steel Housing, Sensing Element (Pressure/Contact/Optical), Electronic Circuitry
Technical Parameters
  • Sensor dimensions for integration into door assemblies (mm) Standard Spec
Components / BOM
  • Sensing Probe
    Direct contact or proximity detection of seal surface
    Material: Stainless Steel
  • Signal Processor
    Converts sensor readings into electrical signals for control systems
    Material: Electronic Components
  • Mounting Bracket
    Secures sensor to door frame or sealing mechanism
    Material: Aluminum Alloy
Engineering Reasoning
0-100 kPa differential pressure
Seal gap detection threshold: 0.5 mm displacement or 10 kPa pressure differential loss
Design Rationale: Hall effect sensor saturation at 150 mT magnetic flux density, causing signal clipping when ferromagnetic seal material exceeds proximity limits
Risk Mitigation (FMEA)
Trigger Electromagnetic interference from adjacent 480V AC motor drives
Mode: Signal-to-noise ratio degradation below 20 dB, causing false integrity readings
Strategy: Shielded twisted-pair cabling with ferrite chokes at 100 MHz cutoff frequency
Trigger Condensation accumulation on sensing surface at 85% relative humidity
Mode: Capacitive coupling distortion exceeding 15 pF parasitic capacitance
Strategy: Conformal coating with 0.1 mm thickness IP67-rated silicone encapsulation
