BF120 3AA 120 Ohm Strain Gauge High-Precision Resistance Foil Weldable Surface Circuit

BF120 3AA 120 Ohm Strain Gauge High-Precision Resistance Foil Strain Gauge,Weldable Strain Gauge Surface Strain Gauge Circuit (BF120-3AA)

BF120 3AA 120 Ohm Strain Gauge High-Precision Resistance Foil Weldable Surface Circuit

Resistance value: within 120 ± 1O Sensitivity coefficient: 2.0 ± 1% mV/V Deviation from the average: =0.3O Base size(L*W) : 6.6 * 3.9mm Wire grid size(L*W) : 3.0*2.3mm Lead: 15 cm insulated electronic wire Power supply voltage: 3-10V Lead specifications: silver-plated or enameled wire 3cm Base material: phenolic-epoxy Wire Shed Material: Imported Constantan Strain limit: 20000um / m Applicable temperature: normal temperature: -30 ? to 60 ? Room temperature insulation resistance: 10000MO Mechanical lag: 1.2um / m The resistance change of the strain gauge is very small, and there must be a proper circuit to detect the slight change. We usually choose a circuit in which the change of the strain gauge resistance can control the circuit, so that the output of the circuit can be similar to the resistance change. The electrical signal (voltage or current) can then be properly processed (amplified).
