Strain Gauge Wheatstone bridge using NI USB 6008

[iztlftri]

Hi, 

I need to use Strain Gauge Wheatstone bridge at LabVIEW by using NI USB 6008. How to do block diagram for strain gauge Wheatstone bridge at LabVIEW by using NI USB 6008 to generate voltage?

Do you want to "generate" a voltage (to supply the bridge) or to you want to "measure" a voltage (signal from your bridge)?

Please be as clear as possible with your desciptions/questions!

To answer your question:

Start with all those example VIs in the example finder explaining all the DAQmx possibilities!

There are examples for "generating voltages" and for "measuring voltages" - and they all come with a block diagram…

Strain gauge measurement requires excitation. USB-6008 does not support providing excitation. The best is to use specialized strain gauge modules with built-in excitation features.

Measuring Strain with Strain Gages

Use NI DAQ Devices for Load, Pressure, and Torque Measurements
