Phidgets PhidgetBridge 4-Input 1046_0B
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.
Connection and Compatibility:
Load Cells
You can connect up to four load cells to the PhidgetBridge in order to measure the amount of strain in the cell. See the product page or manual for your load cell to learn how to hook it up. We have a variety of types available to measure different types of strain: shear, compression, and tension.

Strain Gauges
Strain gauges are ideal for situations where you want to monitor the strain in a material that's already a part of your project. By attaching strain gauges in a strategic way, you can effectively turn a load-bearing member into a custom load cell. You can read strain gauges using the PhidgetBridge by connecting them

USB Cables
Use a USB cable to connect this Phidget to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.
