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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for the price *by on Reviewed in the United Kingdom 1 August 2025* 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. ### ⭐⭐⭐⭐⭐ Very useful Excellent *by on Reviewed in the United Kingdom 12 November 2020* Very useful Excellent ### ⭐⭐⭐ fair quality *by on Reviewed in Sweden 5 May 2023* hard bonding , not strong extension ## Frequently Bought Together - YOUMILE 10Pcs BF350-3AA BF350 350 ohm High-Precision Pressure Resistance Strain Gauge - Hemobllo Strain Gauge Load Cell, Test Sensor Strain Gauge Amplifier, Weight Bend Sensor Test Module Sensor For Arduion Scale --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/158981330-10pcs-bf350-3aa-bf350-350-ohm-high-precision-pressure-resistance](https://www.desertcart.sg/products/158981330-10pcs-bf350-3aa-bf350-350-ohm-high-precision-pressure-resistance) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-30*
