4 MAINTENANCE
The Micro Pressure Sensor has been designed to minimize user maintenance. To keep the
instrument in top condition the following maintenance is required:
After each deployment, the Micro Pressure Sensor case should be washed thoroughly with
fresh water.
Rinse (with freshwater) and dry the connector if contamination with saltwater is suspected.
Saltwater inside the connector will eventually corrode the contacts causing intermittent
communications.
Caution:
The pressure sensor is fragile. Contact with a sharp object to the pressure sensor face
could damage it.
4.2 Main O-Ring Maintenance
Normal use of the Micro Pressure Sensor will not require the main O-ring to be changed.
However, the main O-ring may be inspected periodically and greased to keep the O-ring
in good condition. If during an inspection damage is suspected please do the following.
Note: Do not use sharp objects to remove the main O-ring from its groove.
1.
Using the method outlined in
Figure 4.0
, use the thumb and index finger to remove
the main O-ring from its groove.
2.
Clean the O-ring using a tissue or clean cloth.
3.
Inspect the O-ring for cuts or nicks. An eyepiece or magnifying glass will help.
Replace if necessary.
4.
Clean the O-ring groove located on the end cap with a swab or tissue.
5.
Inspect the O-ring groove for scratches or dirt.
6.
Lightly coat the O-ring with silicon grease and replace it onto the end cap.
7.
Clean the O-ring surface located on the inside of the pressure housing with a swab or
tissue.
8.
Inspect the O-ring surface for dirt or scratches.
9.
Lightly coat the O-ring surface on the inside of the pressure housing with silicone
grease.
