strain gauges are almost always used in a bridge configuration with a voltage or ... will generate some initial offset voltage. ... Connection of Half-Bridge Strain Gauge Circuit.

Hope it helps.

Answer 2

hlo mate ✌️

I have a Wheatstone bridge consists of four strain gauges in a Full bridge pattern. I have a 4volt in the output of my amplifier(AD620) while there is not any force. Why this offset exists and how we can decrease it.(I used a 22megaohm after output of amplifier but it just reduced the offset by 3volts.)

Hope it helps ❣️
