Technical details and manufacturing context for Detection Probes

Definition
Detection probes are the sensing components within leak sensors that directly interact with the monitored environment to identify leaks. They convert physical or chemical changes (such as pressure drops, fluid presence, gas concentration, or temperature variations) into measurable electrical signals for the sensor system.
Working Principle
Detection probes operate by responding to specific environmental changes indicative of leaks. Common principles include: 1) Conductive probes detect liquid presence through electrical conductivity changes; 2) Capacitive probes sense dielectric constant variations; 3) Ultrasonic probes detect sound waves from escaping fluids; 4) Optical probes use light scattering or absorption; 5) Thermal probes measure temperature differentials. The probe generates an electrical signal proportional to the detected change, which is processed by the sensor's electronics.
Common Materials
Stainless steel, PTFE (Teflon), Ceramic, Gold-plated contacts

Engineering Reasoning
0.1-100 bar pressure, -40°C to 150°C temperature, 0-14 pH range
Pressure > 120 bar causes diaphragm rupture, temperature > 180°C degrades piezoelectric crystals, pH < 0 or > 14 corrodes sensing electrodes
Design Rationale: Diaphragm material yield strength (316L stainless steel: 290 MPa), Curie temperature of PZT-5A piezoelectric crystals (350°C), Nernst equation electrochemical potential breakdown
Risk Mitigation (FMEA)
Trigger Electrochemical polarization exceeding 1.2V at sensing electrodes
Mode: Electrode passivation causing 95% sensitivity loss within 24 hours
Strategy: Integrated potentiostatic circuit maintaining -0.3V to +0.8V reference potential
Trigger Capacitive diaphragm fatigue at >10⁶ pressure cycles above 80% yield strength
Mode: Diaphragm microcracking leading to ±25% measurement error
Strategy: Dual-redundant diaphragms with 0.1mm Hastelloy C-276 backup layer
