Mounting the 50kg Bathroom Scale Load Cells to a Board
Ғылым және технология
An update to the previous 50kg Bathroom Scale Load Cells tutorial:
• Arduino Scale with HX7...
I forgot to mention some critical details about mounting the 50kg bathroom scale load cells to a wooden board. It is important that the strain gauge has room to move up and down. The easiest way to achieve this is to 3D print a mounting frame for it. Alternatively, you could also drill a hole to your weight plate.

Thanks for your video. Nowhere else does anyone mention this critical part of mounting these load cells.
Good description. The strain gauges are mounted on the top face middle arm between the outer and the inner squares, and are intended for one to compress and one to stretch as load is applied like a 'Z'. Your ring support makes it so the bending is concentrated on the middle bar.
i was looking for sollution why my scale doesnt work for 5 days. Now i know why! Thank u so much :D
Thanks. That was exactly the information i was after.
Nice explanation, thanks
That's Superb and we can get Correct Readings ......Following this ...

Hey! Did you get it working?
Hey, I was wondering if you knew what size screws are used to connect these mounts to the board? Love the video, thanks!
Hello! I am going to use 4 independent different weigh calculators in my project. Each one will be seperated from each other. Can I use these 4 Load cells with a single hx711?
Hello, a query do you have the design of the housing that you did to the cell please, I need that to be able to print it in 3D, thanks for the video.
Can I connect 2 of these load sensors in parallel to do a comparison of weight of 2 different objects?
I tried to print from the file you shared, but I can not do it because it says it has grouped models. I am new in this 3D printing area. Can you help me? Maybe share a file with the two pieces by separate? Or tell me which online service I can use to print your design. I would really appreaciate it.
hey can I ask about the wire of load sensor what kinds of wire?
Can I use 4 weight sensors with different weight can you answer me please🙏
can you like the stl file for that mount?
Nice explanation. I want to use a 50 kg load cell. but in the code available for 10 kg full bridge load cell . could you please tell me whether i need to make any change in the code.(Aurdino uno)

Hey! The code is the same as long as you are using the HX711 amplifier module.
Can I get the exact dimensions of this load cell??
Nice video. Can you tell me, is there any other option if you don't have a 3D printer to mount without gluing the load cell down (or routing out a hole in the board)? Can I made something or buy something cheaply and easily (off the shelf components at a hardware store) that will allow me to mount the load cells off the board a few millimeters and keep it in place? Thanks.

Hey! I tried to search for a mount for the 50kg cell but couldn't find anything that you can just buy. It seems you need to make it yourself somehow.

@@IndrekL Thanks, I bought a router kit for my Dremel and think I will just cut it manually out of some wood blocks and try to make something similar to what you 3D printed. Thanks, great video! Can't wait to finish the same project, following every step.
I'm trying to make a pull measuring device for archery with a single cell like you've wired up. But I want to read 0% at relaxed and 100% at full draw. I don't really care about the weight itself just the range. Is there a way to have scale.read() return 0 to 100 range? thx

You can calibrate it in software as needed. You can define anything equal or smaller than X as 0% and above Y is 100%
I noticed on the ohm meter, there was no change in resistance when pressing on the part that is in contact with the board, only when pressing on the outer most part of the tab. Is this going to cause a reading issue with the arduino?

I had to press on the very edge to get visible change with a multimeter. the HX711 module can measure much smaller change and amplify it for Arduino.

Indrek thanks! I figured this out when I set everything up and ran the calibration program. It really is sensitive/finicky and is only as good as the solid fixture and wiring.

Indrek Indrek thanks! Can you do a tutorial on how to interface the load cells via analog pins? One tutorial with HX711 to analog (if possible) and one with the TI INA129P amplifier? Thanks!
link to the STL?
Beautiful but where can I buy those plastic supports for the load cells?

You can download the STL files and then 3D print them if you find someone with a 3D printer.
hey, i am doing a prototype for my project. can you please share the 3d file of those bracket. pleeeeeeeeaaaaaaaaassssssssssssseeeeeeeeeeeeeeeeeee
Hey , can i apply tensile force measure the force in kgs? And also can you please mention the size of the load cell!

Hey! The shape of this load cell is designed for compression. It is much easier to put it between two services than hang something to it. In this video I am using this load cell: www.banggood.com/custlink/vKvm7DdKcl It is 34mmx34mm

thanks ! please find some better music - i'd rather listen to polystyrene squeaking on ballons !
