Wheatstone Bridge or PhidgetBridge pros and cons is one a better option

Postby SteveColorado » Wed Aug 23, 2017 5:22 am

I will have 4 load cells as input. The 2 options seem virtually the same except that the PhidgetBridge has 4 inputs. Or I could use use 2 Wheatstone Bridges and a Hub Phidget to accomplish the same thing. Anyone have experience with both? What are pros and cons for one over the other?

Both boards have a 24-bit ADC, so actual performance with load cells should be about the same.

1046 - PhidgetBridge
+ 4 Inputs
- Cost $90 USD
- Enclosure sold separately

DAQ1500 - Wheatstone Bridge Phidget (requires HUB0000)
+ Comes with Enclosure
+ Cost $60 USD ($30 plus $30 for VINT Hub)
+ VINT Hub can be used to connect other Phidgets and sensors
- 2 Inputs

It's worth noting that you can get the VINT Hub and two DAQ1500s for the same price as a 1046 if you need all four inputs.
