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.
