Potentiometer and resistor A pot and a resistor can be used as a really simple way of simulating a load cell. Take the following example: 2.5v excitation voltage2mV per volt at full range.2.5v excitation x 2mV per volt means it will output 5mV at full load. A typical 4 pin loadcell connection:1 – 0V2 – […]

A load cell datasheet will typically specify an excitation voltage, for example 10 Volts. This implies that you need to run the device at 10V, but that is not the case. It is the ratio of the input voltage to the output voltage that is all-important, and you can use the load cell at lower […]
