When the DSS Micro factory guy was training us up on their unit he
remarked that if we broke the sensor it was a $500 bill to replace
it. Of course that's probably retail replacement price and
calibrated. If you were rolling your own there are a few tricks to
accommodate cheap accelerometer sensors. I think price goes up with
frequency response.

Thanks Rusty.
Looks like there could be a market for a similar simple unit for less
than $500...

I wasn't the
point man on the balancer quote. I believe it was the personal balancer
which is much cheaper. The Micro Vib does look like a much more capable
unit. I have used the Micro Vib with a tech looking on. Simple system to
use. I have no idea about support, they were trying to sell us a system
and were pretty eager.

Hi Bill,
I did get a quote from DSS today, and also
talked to them about the personal balancer. They seemed fine
to deal with, so maybe it was just me yesterday.
Anyway, the personal balancer is a no frills
unit, that only gives you amplitude, and phase. You have to do all
your own calculations as far as how much weight to put on, etc. The
unit, with no sensors or cables is $1795, and the normal kit they sell is
$2885, but includes two accelerometers, cables, etc. I can easily
see how you were trimming this down to about $2400.
While not fancy, it will do what you need it
to do, but there is an rpm limit of 4800, so you can't balance any engine
parts above that.
I also exchanged a couple more emails with
ACES, and found that they have a 2015 unit, that goes for about $3900 in
a kit. The unit can only acquire data from one channel at a time,
though it is a two channel unit. It and the 2020 both come with
only one accelerometer in the kit though. They originally quoted
the 2020 because I had mentioned it would be nice to do helo blades if
necessary. They did say that you could do rotor blades with the
2015, but it wasn't as convenient.
I plan to call the ACES guy tomorrow, and
decide what to do (if anything) from there.
Thanks,
Rusty
