Load Cell 20kg – Straight Bar Weight Sensor

This straight bar load cell (sometimes called a strain gauge) can translate up to 20KG of pressure (force) into an electrical signal. Load cells are designed to measure a specific force, and ignore other forces being applied. The electrical signal output by the load cell is very small and requires specialized amplification.

Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 20KG and designed to measure force in one direction. They will often measure force in other directions, but the sensor sensitivity will be different, since parts of the load cell operating under compression are now in tension, and vice versa.
