4.6 OILING THE SENSOR PLATE

For the probe to work correctly, there must be no air gap between the
probe tip and sensor plate. This is achieved by using a small amount
of probe tip oil (supplied with each gauge ). The gauge will inform the
user when oil is required.
To oil the sensor plate:
1 Unscrew the probe tip collar (a)
from the probe body (b) and
remove the probe tip (c) from the
sensor plate (d).
2 Apply a small drop of probe tip oil to
the sensor plate (d).
3 Refit the probe tip and probe tip
collar to the probe body.
Note: The use of normal oil is not recommended as it could damage the probe tip and
affect the accuracy of the gauge. Ultrasonic couplant can be used as an
alternative however, the probe tip and sensor plate will need to be cleaned more
regularly and couplant re-applied more frequently.
Note: A Material Safety Data Sheet for the probe tip oil supplied by Elcometer is
