Load Cell Simulator Circuit Diagram. Image courtesy of amazon. Independently a load cell simulator will be required.
For a few possible load cell mechanical setups check out the hookup guide with the load cell setup. This particular load cell is commonly referred to as a straight bar load cell or a parallel beam load cell. Afterwards we will complete the circuit for a real load cell where it is necessary an additional circuitry that allows obtaining a high precision sensor.
Procedure for testing is.
Most strain gauge load cells work in very similar ways but may vary in size material and mechanical setup which can lead to each cell having different max loads and sensitivities that they can handle. Attached is a tech note that outlines the construction of a load cell simulator. First of all we will show the basic working circuit of a load cell based on a wheatstone bridge and strain gauges. Mount sg2 sg4 approximately at location shown.
