Shock pulse measurement

Measuring points for the SPM techniques are normally
set up in Condmaster and then downloaded to
Leonova. However, it is possible to open the Leonova
default file in the SPM window (1) and configurate all
measuring parameters. Select ‘SPM HD’ and open
with ENTER.
Transducer
Before starting measurements, make sure that the
shock pulse transducer you are using with your
Leonova is properly selected.
Default transducers for the shock pulse techniques are
set up via the transducer register. Default transducer
is the active transducer when ‘Portable’ transducer
is selected under ‘Measuring point data’. To select a
default transducer, see Chapter A page 15.
You can select other shock pulse transducers from the
transducer register (2) if you switch ‘Transducer’ from
‘Portable’ to ‘Remote’.
When using a DuoTech sensor all fields displays (3)
that normally apply to a vibration transducer. The
actual data for the individual transducer is written on
its calibration card. This data should always be input
in the transducer register. When several transducers
are in use, they should be marked to assurethat the
readings are calibrated. Note that measurements with
DuoTech will be performed at channel VIB-1.
HDi
For a normalized reading of bearing condition with the
Leonova default file, go to
MENU > ‘Measuring point
data’ and set the initial value HDi. The default setting
is HDi = ‘Calculated’, which produces the normalized
shock values with condition status display.
If known, the HDi can be input directly via the
keyboard. Mark the ‘HDi’ row, then press the F1 key
(‘Edit’).
If the HDi is not known, input the rotational speed
(rpm) and the shaft diameter, and Leonova will calcu-
late and display the HDi for you.
There are two alternatives for entering the shaft
diameter. ‘Input ISO bearing number’ (4) opens a
window (5) where you set the
last two digits of the
ISO number using the
UP/DOWN
arrow keys on the
Leonova keypad.
‘Input diameter’ (6) opens the Leonova keyboard.
Write the shaft diameter, then edit RPM and input the
rpm on the keyboard.
