10/07 Installation and Maintenance Manual 5
3. Installation
3.1 General Requirements
Observe the following before installing a conductivity cell. Specific requirements for particular types of
installation are given in Sections
3.3 and 3.4.
• Do not remove the Teflon sheath on 1or 10 constant cells, as this will change the cell constant value.
• Do not use the cell in solutions which can affect the fittings or the cell materials. If in doubt, contact
Honeywell.
• Avoid all chlorinated hydrocarbons.
Titanium and PES (0.01 and 0.1 cell constants) and Graphite, Teflon and PES (1.0 and 10 cell
constants) are the only cell materials in contact with measured solutions. These materials are inert to
corrosive chemicals such as mineral acids, oxidizing agents and caustic solutions.
• Avoid trapped air; see that air is not trapped in the cell flow channels.
• Do not use the cell in solutions having temperatures or pressures greater than the maximum limits
stated in the Specifications.
• Avoid locations where the operator must take an awkward position to install or remove the cell.
• When tightening, do not exceed the torque limits provided in Section
3.5. Over-tightening can break
the cell or severely stress it causing cracks to develop, leading to eventual malfunction.
3.2 The Differences between the Quick Disconnect and Integral Cable
Option
The cable options of quick disconnect and integral cable do not affect the performance of the cell. These
options only relate to how the cell is connected to the instrument.
ATTENTION
• The electrical connections are different for these options. Please refer to Section 4 for instructions.
• The wire colors for the integral cable and quick disconnect option are not the same.
• Integral cable means the cable is potted into the cell. The cable and cell are one entity and cannot be
separated.
• The quick disconnect option means the cell is connected to the cell by a receptacle on the top of the
cell. The cell and the cable are separate entities. When the time comes to replace the cell, the cable
does not have to be replaced. The cable can simply be mated with another cell that has the quick
disconnect option. This option can not be used in immersion applications.
ATTENTION
The quick disconnect cable can be purchased from Honeywell.
