Which DAQ can accommodate 5 s-shaped load cells?

I need to make a 5 force balance system with 5 s-shaped load cells. Does anyone have any suggestion on which DAQ I can use? Hopefully one that doesnt cost a fortune.

Thanks!

Hi @Nonsuch and welcome to our forum.

You could maybe use VINT Hub Phidget and Phidget VINT Wheatstone Bridge Sensor Interface (or Phidgets PhidgetBridge Wheatstone Bridge Sensor Interface (w/ Enclosure)).

See links to these products:

Here is one connection example:

Could this work for you?

That does help!

So can I plug two Wheatstone bridge sensor interface devices into one hub in order to accommodate for five load cells?

What programs would be compatible with this set-up?

Also would I still be able to have separate readings from each sensor?

Thanks!

The only thing I am still not sure about: can I plug in two wheatstone bridge interface into one hub and still get seperate readings for all 5 sensors?

Thanks!

Yes, you should be able to do that.

I didn’t try it personally, but what would be the benefit of the module with more load cells if you cannot read them separately?

Oh, would this setup produce separate readings?

I think it should :slight_smile:

I cannot confirm since I didn’t use it…
