DYMH-103 500KG Mini Tension and Compression Force Sensor Inline Load Cell Weighing Miniature Pull Rod Pressure Sensor Portable Crane Scale

I got this for testing 3D prints, particularly tensile strength.The unit operates within the excitation voltage (0-10VDC), I ran (photo) a basic scalar test to give a rough Magnitude of Order just to give an idea of the ratio of mV to pressure and I will say the Instant Repeatability Backlash is very good however; for my needs I find the error rate of 1.0-1.5mV/V w/ a 10+/- variance is too far for me.For my test setup I didn't use any Load Cell Indicator rather I built my own circuit utilizing a lab grade Digital Force Gauge and depending on your needs as is the case w/ me I find this better for quantitative measurements not necessarily qualitative.I hope this was HELPFUL.

The one I purchased seemed to be an imitation and broke after a couple months of use. Mine had a Dymh-103 sticker on the side, I peeled it off and it’s really a clone that you can order from China for a third the price.

Husband is conducting yet another experiment on weight and pressure between two items, and this device helps him do that. He's looking at finding different uses for this device.
