Foil Resistance Strain Gauge
1.A resistive strain gauge sensor with a 350-ohm nominal resistance which varies when a force is applied. By measuring the change in the resistance of the sensor, a measurement of the force applied to it can be obtained.
2.The strain gauges exhibit small changes in resistance. Usually used in general metal materials and other similar elastomers.
