High Temperature Sensors

Stoneridge’s family of high temperature (900°C+) sensors use a resistance temperature detector (RTD) which varies directly and linearly with the temperature of its environment.  The ECM utilizes this sensor input to determine differences in air/fuel ratios and other variables that affect exhaust gas emission levels.

Features and benefits
  • Thin film platinum is a proven technology for exhaust gas temperature sensor measurement
  • Fast time response in a closed-tip design offers precise control and robustness in harsh sensing environments
  • Flexible designs in insertion depth as well as straight and bent configurations
  • Global manufacturing and engineering support capability
Typical Applications
  • Control and monitoring of critical after-treatment systems and engine components
  • Diesel particulate filter (DPF) regeneration control and protection
  • Diesel oxidation catalysts (DOC)
  • NOx storage catalysts (NSC)
  • Selective catalytic reduction (SCR) warming and protection
  • Turbocharger (gasoline and diesel) overheating detection
  • Compliance with on-board diagnostics (OBD) requirements
  • Exhaust gas temperature (EGT) measurement
  • Engine protection against critically high exhaust
