3146_0 Full-Bridge Steel Strain Gauge (Bag of 2), 3146
Designed for steel structures, this strain gauge comes in the full-bridge configuration.
A strain gauge is a small sensor whose resistance changes depending on the strain experienced by the structure it is attached to. They are similar to Load Cells, but are useful for applications where the structure has already been built. For example, you could use a strain gauge and a bridge interface to measure the strain on various segments of the chassis of a robot or vehicle.
This strain gauge is designed to be used with steel structures. It can be used with other materials, but using steel will result in the lowest sensitivity to changes in temperature.

Connection
This is a full-bridge strain gauge. For more information on bridge circuits, see the Strain Gauge Primer. Strain gauges require power and produce a small voltage differential when under load. In order to read this small signal, you'll need an amplifier or a board with a high-precision analog-to-digital converter.
