Hey,

I have a 4" rotating, hollow shaft from which I am tring to measure internal
pressure (max 5000psi).  The measurement is no problem, (RPM of the shaft
never exceeds 200) but I am require to transmitt and reconstruct the 4-20mA
pressure signal at a remote (non-rotating :) location.  I only need about 6"
of range.

Anyone know of an "off the shelf" product which can help?  I could use a
device which recreates a voltage or a current signal..... either or.

TIA
