Engine Development
& Validation Sensors

Exhaust Gas Temperature (EGT)

MIMS Type K and Type N thermocouple probes for exhaust gas temperature measurement at pre- and post-turbocharger positions, catalytic converter inlet/outlet, and cylinder-specific locations. Exposed junction tip for sub-second response time.

  • Type K to 1260°C, Type N to 1300°C
  • Exposed or grounded junction
  • Inconel 600 sheath, 1/16" to 3/16" OD
  • Weld bung available (M12×1.5 standard)

Coolant & Oil Temperature

Pt100 RTD probes for engine coolant, engine oil, gearbox oil, and intercooler coolant temperature. Compression fitting or threaded process connections. 3-wire configuration for direct DAS integration.

  • Pt100 IEC 60751 Class A or B
  • −50°C to 150°C range
  • NPT, BSP, or compression fitting
  • 316SS sheath standard

Engine Test Cell Instrumentation

High-accuracy multi-point temperature measurement for engine test cells and altitude simulation chambers. Calibrated Pt100 probes with NIST-traceable certificates for precision thermal mapping of intake, exhaust, coolant, and oil systems.

  • Class AA (±0.1°C) elements available
  • 4-wire for highest accuracy
  • Matched extension leads for DAQ compatibility

Drivetrain Dynamometer

Bearing temperature sensors and fluid temperature probes for transmission and axle dynamometer testing. API 670-style bearing sensors for gearbox housing. Flush-mount RTDs for sump oil temperature measurement.

  • Bearing sensors: Case styles A–D
  • Pt100 sump/pan RTDs
  • Vibration-qualified MIMS constructions
