PhidgetBridge 4-Input
Product Code: Phidgets 1046_0
This Product has been Replaced by newer version of Phidgets-1046_0
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.
