PhidgetBridge 4-Input
Product Code: Phidgets 1046_1
Description
This board is needed to measure the output from a load cell. You can connect up to four load cells or strain gauges.
Note: The 1046_0B is identical to the 1046_0, except that it comes pre-assembled in a plastic shell enclosure and you have the option of which length of USB cable you want to include.
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.
