Measurement of temperature using RTD and Thermocouple and perform the data logging using LabVIEW and NI modules 9217 & 9211 respectively.

Objective:

Measurement of temperature using RTD and Thermocouple and perform the data logging using LabVIEW and NI modules 9211 & 9217 respectively. Design the front panel as shown in the fig.

Apparatus required:

• 3 wire RTD
• K type thermocouple
• NI 9211 TC module
• NI 9217 RTD module
• NI USB chassis 9178 with USB cable and power adapter.

Procedure:

• Connect the chassis 9178 to the PC with USB cable and give power to it through power adapter. Don’t switch ON the power.
• Connect the RTD and Thermocouple with their respective module as per the diagram shown below: 

• Connect the modules in the chassis slot and switch ON the power to the chassis.
• Open the LabVIEW software and create a new VI. Bring the ‘DAQ Asst’ VI into the block diagram by right clicking over it go to Express------>Inputs-------->DAQ Asst.
• Select the proper DAQ NI 9211-----> Acquire Signals----->Analog------->Temperature--->TC0 (for Thermocouple) click on finish.
• A configuration window will be opened, select type of thermocouple as ‘K’ and click on OK button.
• Now the LabVIEW will configure the DAQ and Build it.
• Take another DAQ Asst for RTD in the VI. This time select the DAQ as NI9217 and Temperature as RTD.
• In the configuration window select ’3 wire RTD’ and click on OK button.
• The output data from both the DAQ are in degree Celsius temperature directly.
• Log temperature from both the DAQ in the following format:

Date	Time	RTD Temperature	Thermocouple Temperature	Status

Note: For the status give a high and low threshold limit of the temperature, within that limit the temperature is ‘NORMAL’ otherwise ‘ABNORMAL’
