Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 1.5 bar
other spec: Immersion depth: 100-500mm, Response time: <2 seconds
temperature: 800°C to 1800°C
Media Compatibility
✓ Molten aluminum alloys ✓ Molten steel grades ✓ Molten copper alloys
Unsuitable: Chlorine-rich or highly oxidizing atmospheres
Sizing Data Required

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal shock cracking
Cause: Rapid temperature changes causing differential expansion between protective sheath and sensor element, leading to ceramic or metal fatigue and fracture
Chemical corrosion and slag buildup
Cause: Exposure to aggressive molten metal chemistry (e.g., aluminum, zinc alloys) and fluxing agents that degrade thermocouple materials and create insulating deposits
Maintenance Indicators
  • Erratic or drifting temperature readings despite calibration
  • Visible physical damage to thermocouple sheath (cracks, bulging, discoloration) or excessive slag accumulation
Engineering Tips
  • Implement gradual preheating protocols (using auxiliary heaters) before immersion to minimize thermal shock stress on sensor components
  • Use chemically compatible sheath materials (e.g., alumina for aluminum, silicon carbide for iron-based metals) matched to specific molten metal composition and regularly clean slag deposits during scheduled downtime

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 - Quality Management Systems ASTM E230/E230M - Standard Specification for Temperature-Electromotive Force (emf) Tables for Standardized Thermocouples CE Marking - Directive 2014/35/EU (Low Voltage Directive)
Manufacturing Precision
  • Temperature Accuracy: +/- 1.5°C or +/- 0.25% of reading (whichever is greater)
  • Response Time: 90% of final reading within 5 seconds
Quality Inspection
  • Calibration Verification against NIST-traceable standards
  • Thermal Shock Resistance Test (rapid immersion from ambient to molten metal temperature)
