Probes for Industrial Gas Sensors

Silicon Carbide Protection Tubes

Saint-Gobain Performance Ceramics & Refractories’ silicon carbide tubes are an ideal solution for protecting industrial gas sensors from the challenging operating conditions typically associated with combustion and flue gases, for example:

  • High temperatures
  • Chemical corrosion
  • Abrasive dust particulates
  • Mechanical vibration
Benefits
  • Excellent thermal & abrasion resistance
  • Mechanical and chemical stability
  • Ideal for use as small, precision components
Application

Gas sensors designed to analyze combustion by-products and flue gases such as oxygen, CO, CO2, CH4, NOx, SOx, and H2S from a wide range of industries, including:

  • Oil and gas
  • Coal
  • Chemicals
  • Glass
  • Cement
  • Pulp and paper
  • Steel
  • Non-ferrous metals and alloys
