ECET-402 Lab1a Temperature Sensors & Controls

  Name: ECET-402                              Week 1 Lab Worksheet    Temperature Sensors & ControlsPlease complete this worksheet and submit to week 1 lab dropboxThis worksheet serves as coversheet 1.      From Part A, step 1(b) of lab instructions, change the temperature from 0 to 30° C and record the corresponding RTD resistance in Table 1.  2.      Graph the temperature-resistance characteristics of RTD below: 3. Is the graph obtained in step 2 above linear (a straight line)? 4. Use the graph obtained in step 2 above to determine the resistance of RTD at 75° F. 5. What is the value of resistor R1 found in Part A, step 3(f)? 6. Paste your Multisim circuit from Part A, step 4 below: 7.  Briefly describe how the circuit above works: 8.  From Part A, step 6 of lab instructions, how would you modify the circuit so that the LED indicating an air-conditioning system is turned ON for temperatures of 68° F or higher? 9.  For the hardware experiment, we would like to set the threshold to 85° F instead of 77°F.  Describe how you would modify the circuit to achieve this goal. Would you increase or decrease the values of resistors? Which resistors?
