This lab involves measuring the responses of 3 temperature sensors for both rising and falling temperatures.

• Here are the links to the actual lab sheets.
• Measure Temperature Sensor Time Response
• Temperature Sensor Dynamics Analysis
• Here are links to basic information about the sensors
• Thermistor
• Thermocouple
• LM35 Integrated Circuit Temperature Sensor

• Here are links to LabVIEW programs to do the measurements.

• NTempsHydra.vi - to measure temperature from the Hydra.
• NVoltsHydra.vi - to measure voltage from the Hydra.
• ResetHydra.vi - A "sub-vi" you need to reset the Hydra.
• 1Temp.vi - A sub-vi that will take one temperature measurement on the Hydra.
• 1VoltHydra.vi - A sub-vi that will take one voltage measurement on the Hydra.

• At the conclusion of the lab, each student should have an electronic copy of the six (6) data sets.
• After the lab, students should hand in analyses of the data, determining the time constants (both up and down) for the six data sets.
• Data sets should be analyzed using as many of the analytical methods as possible.
• 37/63% method
• Initial slope method
• Curve-fit/Logarithmic method.
• Discrepancies in results - especially differences between time constants for rising and falling data - need to be explained.
• As a hand-in homework problem do what is requested in the problem for Dr. Abner Mallity.

• Sensors
• Thermocouples
• Boards with resistor in series with thermistor.
• LM35 Boards.
• Voltmeters
• Oscilloscopes
