Me and my crew are working on a project for a ‘‘Still Rings’’ system. The crew is building an
adjustment to the system where we measure the tension in 4 steel cables with 4 dynamometers.
The only problem is that we need to transport the tension value, measured by the dynamometer, to let a controlbox know that 4 lineair actuators need to move a frame. The question is, how do we get the value from the dynamometer to another system. Is this possible? I really hope someone can help me out with this problem.
The Dynamometers you selected don’t have any output other than an LCD. In addition, there’s no information about hte control box to know how to communicate with it. This is one of the risks you run when trying to save money and purchasing directly from China. With the pages you provided, we can’t see any way to link anything together, even with a microcontroller. Your Dynamometer would need some sort of output (serial, analog, I2C, RS485 etc), and we’d need to know how to communicate with the linear actuator control box.
You’ll need to provide a lot more information about what you are using before we can provide any suggestions. What is the output of the Dynamometer? What is the “other system” you want to send this data to?
The 4 cable tensions need to be measured, the only correct approach to do this is with 4 dynamometers. We selected those in the budget we have: alibaba.com/product-gs/761460851/aluminium_dynamometer_crane_scale.html?s=p
I searched for a dynamometer with outputs in a higher price class, but I can’t find any of those (tips?)!
The second part of the Still rings situation is that we have 2 lineair actuators connected to 1 control box in the upper frame of the system. This part of the system is used to lower the upper bar with a screw to adjust the damping of the system. What we would like to achieve is to combine the ‘dynamometers’ with the ‘control box & lineair actuators’ to control those in 1 interface. At this point I think it’s nog possible with the current set-up. This is why I came to this forum for tips! I really hope this description has enough detail for you.
