Can anyone recommend a good tachometer for use with my vibe analyzer?
I have seen in classes and in the field where other people have laser tachometer's that mount onto tri-pods that will function even up to 3 or 4 feet away from the rotating shaft, but I have yet to be able to find out who makes them.
I use (see picture) a laser tach that I bought from The Modal Shop and I mount it to a magnetic dial indicator base. The problem is that it is VERY sensitive to vibration of the indicator base. If I can't position the bases flexible arm in the SHORTEST AND MOST RIGID manner possible, I get skewed speed readings which is pretty frustrating.
I have used small indicator bases and gigantic ones that weigh 15 lbs.... still seem to have the same issue with tachometer vibration.
Was curious what every one used and if you could recommend something?
