Question
This sensor uses the differential expansion of two dissimilar metals. ___ These sensors use a temperature-induced change in the resistance of a material to measure temperature. ___ When using the 2-wire method for the RTD, . this induces a small error. ___ In contrast to the RTD detector, this devise has an inverse temperature curve. ___ This detector consists of two dissimilar metals, joined at one end to cause a voltage at the measuring junction. ___ This type of sensor is especially useful for measuring the temperature of surfaces that cannot be reached or touched. ___ This type of sensing element is most often constructed of Platinum or Nickel. ___ This detector's reading is made more accurate by measuring the cold junction temperature. ___ This detector measures infrared radiation flux. ___ This temperature detector is used in gas heating systems around the house. ___ Thermistor Resistance Temperature Detectors (2x) Lead-wire resistance Radiation Pyrometer Bimetallic strip Thermocouple (3x)Explanation / Answer
