Precalibrated IRt/c’s

PreCalibrated Non-Contact IRt/c’s (Infrared Thermocouples)

Self-powered. Non-electronic, no-fail construction. MTBF (Mean Time Between Failure) rate >1,000 years, IRt/c sensors’ technology make them the most reliable sensors on the market. Best used for low temperatures (< 500 °F) and non-metal or coated metal surfaces.

  • Intrinsically Safe
  • Fast Response time
  • Calibrated to match conventional thermocouple at a specific temperature.

Principles of Operations

By adjusting the calibration setting (c) of the IRt/c to equal the Seebeck coefficient (α), the signal output (mVout) will be within 2% linear to match the conventional t/c at temperatures close to the calibration point.
