Abstract:

A shaft mountable, portable, low frequency FM transmission device for communicating rotating shaft mounted sensor information to a stationary platform. It includes a generally cylindrical, dynamically balanced sending unit attached to and encircling the shaft and a remote stationary receiver having a preamplifier and pickup loop encircling but not touching the sending unit. Information from shaft mounted transducers is transmitted from the shaft to the receiver using low frequency FM techniques. Low frequency FM operates at low power which permits use of small batteries containable in a reduced volume, requires minimal receiver electronics, allows undistorted signal transmission at high RPMs and is relatively insensitive to axial and radial shaft movement. author
