Ultrasonic Distance (Displacement) Sensor Functions Test Trial 

Distance sensors (transducers) are just that, they provide electrical signal representation of a physical value, such as distance to an object. Automated machinery can be adapted to use the signal as a reference of part position, orientation, etc. At one of my work places, a distance sensor was used to calculate the diameter of rolled material coil, to start rolling it at right rpm, for the entire machine fed material at constant rate. Towards the end of that coil, the machine “knew” to warn the operator of low material, because of the distance.

Tinkering Nerd understood. Am I right that accuracy is not very high?

Tin Woodman's Workshop my guess that these can be down to 0.5mm accuracy, maybe even smaller. A lot will depend on ADC (analog to digital converter).

There must be! Example: police speed radars. They detect you before you can see them. Cheers.

@@TinkeringNerd thanks bro.

Check eBay. They have something like this.

Also what is the maximum range of this one?

This sensor will not work from 5V power supply. It outputs both 4-20mA and 0-10VDC analog signals. It measures from 4 to 40 inch.

I had it, then sold on EBay. If not mistaken, I think it is called Gordy’s sensors. Cheers

Thank you for your request. I’m not giving up on that CNC project, and am asking for patience. Currently, I’m trying to manage between my job (50+ hours per week), family (4+ kids and wife), and all kinds of obstacles (both physical and financial) in the shop, to finally finish the machine. Please, hang in there, I’m working on it.

Ill be here. Take your time. Im Excited to see how it turns out. Im retrofitting a fryer mill with Dmm-tech servos and possibly a syntec control.

I looked at dmm-tech servos as well. The dyn4 system gets almost in the same bulk as some brand name units. Just couldn’t have it! :)

I even acquired a 3kw power supply for dyn2 setup.. but, never got to it.. now, I have a very nice power supply just laying there, waiting for it’s moment..

I hope the dyn4 servos work well. I was quoted $2300usd for 3 1.8kw servos (one servo has a brake.), drivers and cables. The 4 axis syntec 21mu control is around 1500usd. Way less the a pre made retrofit like centroid or Seimens sinumerik at around $22,000 but still being a "industrial" set up. That's why I'm really looking forward to more videos. If this system you have works, ill use it on a furture plasma table build
