CAUTION:
• Tensioning of a belt is an important task as it is
related directly to belt life time.
• The use of the referred frequency meter is essential
to apply the correct tension of belts and avoid
excess tension risks, lack of tension, noises and
any other problem arising from an uncorrected belt
tension.
• Engine could be seriously damaged if tensioning
is not carried out following strictly procedures
described for this frequency meter.
CHARACTERISTICS
Instrument outline
• Belt frequency is measured using this checker. The
measure unit is the Hertz (Hz).
• Reading head (A) is constituted by two sensors (a) and (b)
allowing the measurement of vibrations induced at the belt.
• One of sensors takes the reading while the other, located
outside the measuring field, is used as a reference (see
explanations on use of checker).
• Each sensor can be used either as a measuring sensor or
as a reference.
Measuring range: 30 to 520 Hz
Uncertainty:
± 1Hz < 100 Hz
± 1% > 100 Hz
Checker control
• Frequency generator (C), integrated in the visualising dis-
play box, allows checking the correct performance of
frequency meter.
• If the difference in readings between the two sensors is
different than 512 ± 1 Hz, the checker must be inspected
by the manufacturer (see Users Handbook for this kind of
controls).
