Most experienced users of oceanographic equipment replace all O-rings before every deployment as a matter of
routine. The cost of an O-ring is negligible compared with the cost of the instrument and its deployment. Therefore,
routine replacement of O-rings is cheap insurance.
O-rings: #2-225 N70 O-ring (RBR#0002408), #8-225 N90 backup ring (RBR#0009115)
6.4.2 Servicing the RBRquartz BPR|zero waste oil reservoir
Overview
The RBR quartz
3
BPR|zero utilizes a Paroscientific Digiquartz® sensor which is filled with a buffer oil and is connected to
the environment via a tube. The difference between an RBR quartz
3
BPR and BPR|zero is that the |zero makes use of a
valve to change the Paroscientific Digiquartz® sensor or sensors to measure the pressure inside the housing of the
instrument, which is monitored by a barometer in order to correct for the drift of the sensors over time. This actuation
of this valve results in a small volume of buffer oil transferred into the pressure housing of the instrument. The
transferred buffer oil is stored in a reservoir that will need to be cleaned periodically. The instructions in this section will
describe how to open this reservoir and replace the absorbent towel.
Materials required:
Protective gloves
Eye protection
Replacement absorbent towels*
O-ring*
Silicone grease*
*Provided in the maintenance kit
Opening the reservoir
Open the battery end cap as described in Opening and closing the RBRquartz BPR|zero
Remove the umbilical from the battery end cap by pushing down on the latch (located on the left-
hand side of the connector) and pulling the connector down. Do not pull from the wires attached to
the connector, as this could damage them.
