What you have received
A1100 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.
Protection caps
Non-ATEX sensors (A1100)
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 6610 TPA application.
ATEX sensors (A110E)
Only one protection cap will be delivered with each sensor (part number 33051-SG or 33051-H0).
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: The recharge kit for oxygen has a blue sticker on the front of the box.
Sensor recharge kit
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
• a set of five cotton washers
• a set of five silicone discs (available in all 2956A-XXX recharge kits only)
• a set of replacement O-rings
®
• a set of replacement Dacron mesh patches
The black 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
being used once.
The cotton washers provide additional protection against the formation of deposits and residue on
the center electrode and anode, which prolongs the time period required between sensor
maintenance.
