Hi there;
So first thing you should think about is the signal conditioning you will require. The myRIO is an awesome tool but does not include signal conditioning. . For the load cell you will need excitation voltage and you will be reading a resistor value, so you need to build a wheatstone bridge to do so. Have a look at the following link; Measuring Strain Gauges
As for the LVDT; they operate on the principle of a transformer and consist of a stationary coil assembly and a moveable core. An LVDT measures displacement by associating a specific signal value for any given position of the core. LVDT signal conditioners generate a sine wave for the primary output signal and synchronously demodulate the secondary output signal. The demodulated output is passed through a lowpass filter to remove high-frequency ripple. The resulting output is a DC voltage proportional to core displacement. The sign of the DC voltage indicates whether the displacement is to the left or right.
You can take advantage of the FPGA chip in your myRIO and use this example
Finally to save data to excel, you have several ways to do it; the easiest one is to use the Report Express VI or you can use the write to spreadsheet VI.
Hope this info helps
Greetings
