How are we able to know the variable of a Strain Gauge? Answered
Hi, for a school-project I need to measure the weight of an object.
Therefore I am using an old weight-scale.
The component wich includes 2 Strain Gauges has 2 seperated wires coming out and 1 other wire conected to the Ground.
Because we can't find something changing when we measure differend kinds of things, (for example the changing resistor-value) we hope that you can help us.
The two wires coming out of the Strain Gauges are connected to an Amplifier (TL081CP).
The scale itself is a KRUPS TYP 841 ; 871-B
