Q: Infrared optical ______ can be used for measuring and monitoring temperatures and hot spots of jet engine rotor blades.
  • A. Ammeter
  • B. Hygrometer
  • C. Pyrometer
  • D. Machmeter
Correct Answer: Option C - Infrared optical pyrometers can be used for measuring and monitoring temperatures and hot spots of jet engine rotor blades. A probe with silicon detector applicable to jet engine rotors is described. It is designed to measure temperature in the range 1200-2000 degrees F in gases of about 3000 degrees F and 300 psi at rotor speeds exceeding 8000 rpm. A pyrometer is a type of remote sensing thermometer used to measure the temperature of distant objects.
