UNPACKING AND INSPECTION

LOCATION CONSIDERATIONS

SECTION 2 - INSTALLATION

This section contains unpacking and inspection instructions, and special
location and safety considerations.
Following these topics is a table that guides personnel, seeking to perform a
specific installation task, to the proper procedure or procedures needed to
perform that task.
NOTE: Sensor wiring procedures are located in the product instruc-
tion of the analyzer or transmitter used with the sensor.
Examine the equipment upon receipt for possible damage in transit. If there
is evidence of damage, file a damage claim with the responsible transporta-
tion company and notify the nearest ABB sales office.
Carefully inspect the packing material before discarding it to make certain
that all mounting equipment and any special instructions or paperwork have
been removed. Careful handling and installation insures satisfactory perfor-
mance of the sensor.
Use the original packing material and container for storage. The storage
environment should be protected and free from extremes in temperature and
humidity and fall within the environmental specifications listed in Table 1-3.
The Type TB404 sensor employs an encapsulated design that makes it ideal
for aggressive and harsh process streams. Sensor variations accommodate
submersible installations such as tanks and open vessels or waterways, pipe-
lines, and sanitary pipelines and tanks with two-inch tri-clamp fittings. Fig-
ure 2-1 shows the anatomy of the Type TB4042 sensor.
When installing the sensor, choose a location that insures the following:
The solution around the sensing area (Fig. 2-1) must be representative
•
of the bulk solution.
The fluid velocity must not damage the sensing area either by cavitation
•
or abrasion.
The solution must actively circulate through and around the sensing area
•
and must not contain entrained air or vapors.
The sensing area must be perpendicular to the fluid flow path. Figure
•
2-2 shows the sensor orientation requirements.
