The Phidgets PhidgetBridge Wheatstone Bridge Sensor Interface (w/ Enclosure) is needed to measure the output from a load cell. You can connect up to four load cells or strain gauges.The minimum data rate is 8ms though the board has a maximum sample rate of 122 samples a second (slightly less than the 125 an 8ms rate would have you believe).

It comes pre-assembled in a plastic shell enclosure. 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.
