ELECTRODE -VOLTAGE METER MAGNETIC FIELD -COILS METER DIAMETER CONDUCTIVE LIQUID The Foxboro Company Question 1 (6 points) Listen A RTD is used to measure an unknown temperature using the equation RT =RT,[1+ Resistance coefficient (T2-T)]. The following data is recorded: At unknown temperature T2, the resistance is 1875 ohms. At known temperature T- 22 deg C, the resistance is 1070 ohms If the resistance co-efficient of the RTD material is .00382 Find the temperature T2? Solve in a paper, scan and upload here.
