Mounting the STWIN.box - SensorTile Wireless Industrial Node Development Kit

[peri]

I am trying to use the STWIN.box - SensorTile Wireless Industrial Node Development Kit to detect vibration on X-ray tubes. I know the sensor has screw holes but the tube doesn’t have screw holes. I was wondering what other options I had for mounting?

Interesting challenge, a picture of the tubes would be a great start.

This is the tube. Position 1 is the place we were considering placing it. Position 2 is more optimum for vibration but there is a hole there for the tube window and since the sensor is smaller it would not be able to sit there.

I tried to but for some reason it keeps disappearing. It keeps loading instead. I will try to fix this

​@peri  - Did you mean to attach a diagram or picture?

[Andrew Neil]

Glue?

Cable ties?

Make a bracket?

[peri]

We don’t want to use glue since this needs to be easily removable and movable from one tube to the next. The cable ties might work. For the bracket we would still need a way for it to tightly cling to the tube. We were thinking of using a magnet but are worried of the dampening that might occur due to the layers between the sensor and the tube.

Of course - that would be part of the bracket design!

I did nearly suggest magnet(s) - but thought that might affect your X-rays !

 

A diagram and/or picture would really help - Did you mean to attach one to your earlier reply ?

[Andrew Neil]

just one idea of a very simple clamp for attaching to a tube/pipe:

easy to make or 3D print; maybe you can even find one to buy off-the-shelf ...

I had a look at the types of X Ray tubes, there are two types I saw, a large metal box with a round cylinder off to one side and a glass complicated tube.  

If you want competent answers the type or a picture will help craft the answers.  

This is from the Sensor Tile Box pro, how accurate do you want the frequencies,  also FFT work in steps, the most likely solution is mid step.  (Central Limit Theorem beats you every time)

Same sensor, the absolute peak at 7.5 is really rare, like this is the first one I have seen and I have done this for a long time.  

Are you looking at frequencies with the tube in place or just the tube.  Either way one would normally do a Finite Element Model

I would use the MKI210 and 3M SJ4570 Dual Lock™ Low Profile Strips - 3⁄4" x 150'  we did this in Iowa it works a treat and comes off, you can get shorter lengths. 

Your secondary vibrations will be a beast with a stand off device.  

The people here can help, they are really quite good, but you have to help a bit.

I have attached an image above in the first thread. I wasn’t able to do so until now.
