1 Sensor
2 Protection caps
2.3.1 Electrochemical sensor
The sensor may be delivered separately or as part of an ORBISPHERE system, depending on the
individual order.
The sensor will be delivered fitted with a plastic screw-on storage cap to protect the sensor head.
This is held in place with a plastic collar.
A plastic screw-on base is also provided to protect the connection socket, and which also provides a
suitable stand for the sensor during maintenance procedures, and when not in use.
2.3.2 Protection caps
Non-ATEX sensors (GA2400)
Two protection caps will be delivered with each sensor, one without a grille (part number 33051-S0)
and one with a grille (part number 33051-SP).
A third protection cap (part number 33051-SG) is also available as an option and improves the
maintenance interval for beer or soft drinks process applications.
A fourth protection cap (part number 33051-ST) is delivered for the 6110 TPA application.
ATEX sensors (GA2800)
Only one protection cap will be delivered with each sensor (part number 33051-SG or 33051-H0).
2.3.3 Sensor recharge kit
A recharge kit should have been ordered with the sensor as this will be required to initially make the
sensor operational. It is also required for sensor cleaning and membrane replacement procedures.
Note: There are two different versions of the recharge kit. One version for GA2X00/A110X sensors and one version
for C1100 sensors. Refer to the documentation supplied with the kit for instructions on how to use the version of the
recharge kit with the applicable sensor.
The kit contains:
• four recharge cartridges with pre-mounted membrane and electrolyte. The type of membrane
mounted in the cartridge will be specific to the kit ordered
• two anode cleaning tools
• two sets of five cotton washers and five silicone discs (only for 2956A-XXX)
Note: The box for GA2X00 sensors has a blue label and the box for A110X sensors has a black label.
• one set of replacement O-rings and Dacron
sensors
The blue anode cleaning tool is used to clean the anode of any deposits or residue that may have
formed. It is doubled-ended so it can be used for two membrane replacement processes, each end
