## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-21669:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN-21669:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This straight bar load cell (sometimes called a strain gauge) can translate up to 10kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object's weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.

This particular load cell comes attached to hardware that ends with a hook. This allows you to easily install and hang your load cell.

Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation.

The colour code on the wiring is as follows:

- **Red** (Excitation or VCC)
- **Black** (Excitation- or GND)
- **White** (Amplifier+, Signal+ or Output+)
- **Green** (Amplifier-, Signal- or Output-)
