Magnet mounting for non-contact proximity probe
(OP)
Hi,
Any recommended magnet mounting for non-contact proximity probe?it's intended to be used as temporary installation at hydro turbine-generator

Of course if you supplied the mass and geometry of your probe, and the required precision and frequency range, somebody might be prepared to give less accurate but easier advice.

Thanks for your input.
In addition to that, i currently used manually fabricated brackets ( 'L' shape bracket ) for proximity probe installation, however it give less accurate result. And then i'm thinking about magnet mounting instead of using those brackets.Installation also will be done at standstill condition.The measurement will only take place for commissioning of that machine after overhaul works.

On the positive side, I have used magnet mounts with prox probes successfully. The one thing you MUST know is the natural frequency of the probe/mounting arrangement. I find the easiest way is with the machine stopped and then carry out a bump test (I actually "pluck" test). If you find the natural frequency is close to a run speed you will have bad measurements and you will have to modify the support system.
