Precision resistive strain gauge for the pressure sensor, load cell, deformation measurement. BF350-3AA is widely used in product development, student experiments, maintenance, production, etc. the main features of BF350 is high accuracy, good stability, easy to use and suitable for 0.02 level sensor.
- Type: BF350-3AA
- Resistance: 349.8 ±0.1Ω
- Sensitivity coefficient(gauge factor): 2.0 – 2.20
- Accuracy class: 0.02
- Strain limit: 2.0% (2000 microstrain)
- Monolithic size: 7.1mm * 4.5mm
Materials used for making BF350 conductive material is Constantan, copper-nickel alloy 55% copper or 45% nickel as its provide constant resistance over temperature. In substrate backing modified phenolic resin foil is used.
How to Use
The sie of BF350-3AA is 7.1mm * 4.5mm which is too small for handaling , we always recommend pre solder tab with flexible wire which is easy to install. the Applications surface must be polished, remove any oxides, residues before applying adhesive. We recommend adhesives like epoxy glue hot curing adhesive (H-610 or equivalent) for long term use and for short term Cyanoacrylic glues is best.
