50. An important and critical assumption when using two-color pyrometers is that a smooth curve exists between two variables. What are these two variables? a. roughness and calor b. emissivity and wavelength c. emissivity and temperature d. spectral translucence and emissivity 51. Compared to a thermocouple, an advantage of a resistance temperature detector (RTD) is: a. less expensive than a thermocouple b. more linear than a thermocouple c. wider temperature range than a thermocouple d. less stable than a thermocouple
