1046_0 - PhidgetBridge 4-Input


Product Features

The PhidgetBridge is the interface board needed to measure the output from a load cell. You can connect up to four load cells, strain gauges, or wheatstone bridge sensors.

Product Description


The PhidgetBridge lets you connect up to 4 un-amplified Wheatstone bridges, such as:

  • strain gauges
  • compression load cells
  • pressure sensors/Barometers
  • piezoresistive accelerometers
  • Magnetoresistive sensors (Compasses)

The data rate and gain values can be configured in software.
