BF3503AA 350 Ohm Foil Strain Gauge Sensor (Resistance Strain Gauge)
The BF3503AA Strain Gauge Sensor is a resistive foil sensor designed to measure mechanical strain in materials and structures. When the sensor is bonded to a surface, stretching or compression causes a small change in its electrical resistance. This change can be measured using a suitable signal conditioning circuit to determine strain.
With a nominal resistance of 350 Ohm, this strain gauge is suitable for bridge measurement circuits and experimental setups involving force, deformation and structural testing. It can be used in load measurement prototypes, mechanical engineering projects and industrial instrumentation.
