## Description

Type: BF350-3 AA type konstantan metal foil resistance strain gauge Resistance: 350 ± 0.1 ohm Sensitive factor: 2.0-2.20 Precision level: 0.02 Strain limit: 2.0% Dimensions: 7.4mm * 4.1mm Sensitive to grid size: 3.2mm * 1.6mm Temperature range of use: -30~+80℃ Lead Material: 3cm insulation enameled wire Package included : 10 x BF350-3AA BF350 Precision Resistive Strain Gauge

Review: Great for the price - Used these in a half-bridge configuration to measure bending force on an aluminium beam. They do the job perfectly. A tip though - use a good quality strain gauge amp, there are some cheap and nasty ones out there which are useless for measuring.

## Questions & Answers

**Q: Can these be used as weight sesnsors for diy experiments with coin/dispenser?**
A: In theory they could - lots of electronic scales, load cells etc. use strain gauges, fitted to something that's designed to deform, bend etc. in a predictable way when loaded.

If you arranged a metal strip so it bends when loaded, the "outside" of the strip would be extended (the resistance of a gauge here fixed along the strip would increase) - and the "inside" of the strip would be compressed (resistance of a gauge here would be reduced).

If you were to set up something like this, you'd need to be careful to avoid damaging the gauges or wiring. It might be easier to use a ready-made pressure or load cell (load sensor), with a suitable range.

Also, the resistance changes from strain gauges and load cells tend to be rather small - so you need a conditioning module (a specialist amplifier circuit - which Amazon also sell) if you want to use these. These are often used in electronic weighing scales.

**Q: Is this gauge self adhesive?**
A: No, it's not. And it needs to be well stuck down to a suitable bar so that you can measure the stress on it when the bar bends.

**Q: Is it flexible?**
A: yes
