Unpacking and Inspection
Inspect the outside of the carton for any damage. If damage is detected, contact the carrier
immediately. Inspect the instrument and hardware. Make sure all items in the packing list are
present and in good condition. Notify the factory if any part is missing.
Note:
If the sensor is to be stored, the protective boot should be filled with either KCl electrolyte
solution or pH 4.0 buffer solution and replaced on sensor tip until ready to use.
Note:
Save the original packing cartons and materials as most carriers require proof of damage due
to mishandling, etc. Also, if it is necessary to return the instrument to the factory, you must pack the
instrument in the same manner as it was received. Refer to Section 8.0 for instructions.
2.3
Mechanical Installation
The Rosemount 396R Sensor may be installed through a weldalet or in a pipe tee or “Y”, as shown
in Figure 2-1, when used with a ball valve. Insert the end of the sensor to a depth sufficient to ensure
that the glass bulb is continuously wetted by the process fluid. The Rosemount 396R can also be
inserted directly into the process without the use of a ball valve for appli cations not requiring
continuous operation during sensor maintenance.
The sensor must be mounted within 10-90 degrees of the horizontal with the tip pointed
downward, thus keeping air bubbles off of the pH sensitive glass bulb. Bubbles settled on the glass
bulb disrupt the electrical continuity between the pH sensitive glass and the silver/ silver chloride
measuring element.
If the retraction version is to be installed without a ball valve follow the installation procedure for
insertion service (Section 2.3.2). Perform the following steps for sensor installation through a ball
valve:
2.3.1
Installation Through Ball Valve
1.
Carefully remove the liquid filled rubber boot which protects the glass electrode and keeps
the liquid junction wet during shipping and storage. Discard the liquid and boot. Make sure
the lubricated O-ring is in place in the groove inside the male connector on the sensor body.
2.
With the male connector on the sensor’s body, insert the sensor into the ball valve until it
gently touches the closed valve. The molded electrode guard will protect the glass bulb
from breakage.
WARNING
Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.
Allow sufficient room for safe retraction and insertion of the sensor. Personnel should have room for
stable footing while performing removal or insertion of the sensor.
CAUTION
Buffer solution, in the protective boot, may cause skin or eye irritation.
