Rotor balancing
Balancing equipment
For single plane balancing with four runs, the only equipment
needed is a vibration transducer type SLD144 or other IEPE (ICP
®
)
type transducers with voltage output.
The transducer is mounted with a magnetic foot (TRX29) or with an
M8 (UNC 1/4”) screw. It is connected with the spiral cable CAB82
or a straight 10 meter cable CAB83.
For the 2-run methods, a trigger pulse is needed which is either
supplied by a proximity switch or by the SPM tachometer probe
TTP10.
The laser dot from the tachometer probe is directed towards a
piece of reflecting tape pasted on the shaft. The tape must have
a sharp edge.
NOTE: It is very important that the tachometer probe is firmly
attached and not moved during the balancing procedure. The
laser is sensitive to reflections from the shaft, especially during
measurement at short distance. Do not direct the tachometer
probe straight at the shaft, slightly angle the direction in order
to avoid misreadings.
SPM supplies a tachometer probe holder with a magnetic base
(SPM 81319) and a clamp for the probe (SPM 14765).
