500 g load cell is a sensor designed to measure force or weight up to a maximum capacity of 500 grams (0.5 kg). It converts mechanical force (like weight) into a small electrical signal that can be measured and interpreted by electronics.
How it works
Most 500 g load cells use strain gauge technology. Inside the metal body are strain gauges arranged in a Wheatstone bridge. When a load is applied:
The metal body slightly deforms (bends microscopically)
The strain gauges stretch or compress
Their electrical resistance changes
This change is converted into a measurable voltage output
