Combinator Basics

Now that you have a load cell with a strain gauges hooked up to an amplifier, you can now measure force applied to your cell. For more information about how to hook up strain gauges, load cells, and amplifiers go to our hookup guide.

But what happens when you don’t have a load cell with four strain gauges? Or you want to measure something really heavy on something scale like?

You can combine four single strain gauge load cells (sometimes referred to as Load sensors)! Using the same wheatstone bridge principle, you can use a combinator to combine the single strain gauge load cells into a wheatstone bridge configuration where the force applied to all four single strain gauge load cells is added to give you a higher maximum load, and better accuracy than just one, and then the combinator can be hooked up to the same amplifier for easier measuring.

For more information on hooking up load sensors go to our hookup guide.

This is the same layout that you would find in say your home scale. There would be four strain gauge load cells hooked up to a combinator and an amplifier to give you your weight reading.
