Comidox 3PCS BF120-3AA 120Ω 120ohm High-Precision Resistance Strain Gauge Foil Strain Gauge for The Pressure Sensor Load Cell

Comidox 3PCS BF120-3AA 120Ω 120ohm High-Precision Resistance Strain Gauge Foil Strain Gauge for The Pressure Sensor Load Cell

• High precision, good stability and easy to use, suitable for 0.02-level sensors. (Output error is in the range of plus or minus 0.02 at full scale.)
• Substrate: modified phenolic; grid wire: Constantan (copper alloy containing 40% nickel, 1.5% manganese), fully enclosed structure, simultaneous temperature self-compensation and creep self-compensation.
• The resistance strain gauge can be used as a sensitive component and directly used for strain measurement of the tested part;
• It can also be used as a conversion element, and the sensor is constructed by an elastic element for indirect measurement of any other physical quantity that can be converted into strain of the elastic element.
• When measuring with a strain gauge, attach it to the surface of the object to be tested. When the measured object is deformed by force, the sensitive grid of the strain gauge is also deformed, and the resistance value changes correspondingly, and is converted into a voltage or current change by the conversion circuit, thereby realizing the strain measurement.
