3. In-Line Installations
Most of the Conductivity/Resistivity electrodes used with the 2850
can be installed into standard
3 /
4
in. (NPT or ISO 7-R 3 /
4
) fi ttings.
The 2850-5X models are designed for integral systems, where
the electronics are attached directly to the sensor.
The preferred installation for in-line applications directs fl ow
straight into the electrode. This confi guration reduces the
probability of entrapped air bubbles, and provides the best
continuous sampling of the fl uid content.
Use the 2850-6X models for in-line installations where the
electronics must be separated from the electrode. Conductivity
electrodes with sanitary fl ange fi ttings must be installed using this
option.
4. Tank Installations
While the 2850-5X and -6X electronics cannot be submerged, either model will
accomodate tank installation.
Select any electrode with a 5 m (15 ft) cable. The cable may be cut to length, but it
CANNOT BE EXTENDED.
The universal adapter included with 2850-6X models can be attached to the top of a
tank or mounted to a surface near the tank.
Adapt the 2850-5X models to tank installations by attaching a clamp to the conduit.
If the electrode is mounted vertically in a tee, do not recess the
electrode orifi ces inside the tee. Mounting upside down may help
prevent air entrapment.
An oversized tee or fl ow cell may be helpful for inline installations.
At least 4 threads (ANSI B1.20.1) must be engaged to meet the
pressure rating as published in the specifi cations.
