Strain gauge module [SOLVED]
-
I'm wondering if somebody used this strain gauge with Duet3D?
Or can give advice of using it... to not to break my board. -
That module should be compatible with the Z probe input of the Duet 2 series. It's for single-element strain gauges, so don't be surprised if the zero point varies with temperature.

Thanks, David. If I correctly understand better will be using something like that for full bridge configuration with four sensors.
But its output voltage rated from -4 to +4V... Is it ok for Duet board?
-
Yes, a half-bridge or full-bridge sensor used correctly should be less sensitive to temperature.

@uvarovkv Where and how are you going to mount the strain element? Just curious.

Your application requires a very sensitive force measuring device. A load cell sensitive enough for such low amplitude of vibration can work or you could also resort to using other types of sensing techniques but I think they might be costly. You could learn more about the force sensing techniques and related concepts through here: https://tacunasystems.com/knowledge-base/an-overview-of-load-cells/
