Type 8200
Installation, commissioning
Warning
Danger due to nonconforming commissioning.
Nonconforming commissioning may lead to injuries and damage
the holder and its surroundings.
• Before commissioning, make sure that the staff in charge have
read and fully understood the contents of the manual.
• In particular, observe the safety recommendations and intended
use.
• The installation must only be commissioned by suitably trained
staff.
Warning
Gases or liquids can leak out indetected through the seals or
the screws.
• Check regularly the holder for leaks.
Warning
Before initial operation of the holder, or after a long out-of
use period:
• Ensure that the seal is tight.
• Ensure that all parts are in working order.
7.2. Installation onto the pipe
Warning
Risk of injury if the recommendations on installation of the
measuring device inserted into the holder are not observed
(see the relevant operating instructions).
• Take account of the recommendations on installation of the
inserted probe.

Installation, commissioning
7.3. Inserting the probe
The holder is intended only for mounting probes with a
length of 120 mm.
Make sure the welded area has cooled down before
inserting the probe.
→ Ensure there is no damage to the probe or the holder.
→ Check that all o-rings are in place in their appropriate grooves,
and are free of damage.
→ Insert the seal pusher.
→ Screw the probe into the PG 13.5 thread at a locking torque
between 2 and 3 Nm.
7.3.1. Operating mode
When a probe is screwed into the direct welding holder, the
seal pusher presses the o-ring into the space between the steel
frame and the probe shaft. This seals the probe in a manner that
almost completely eliminates crevices and their associated risk of
contamination.
When the probe is loosened, the o-ring relaxes again. This lowers
the friction between the o-ring and the other parts of the assembly,
and the process is no longer sealed.
If this takes place while the process is still under pressure, the pressure
evacuation holes feature (see chap. 7.3.2), automatically comes into use.

Maintenance and troubleshooting
7.3.2. The pressure evacuation holes
feature
The direct welding holder is equipped with a safety mechanism, to
prevent danger to service personnel.
If the probe is unscrewed while there is still pressure in the process,
the o-ring between the probe and the steel frame of the holder loses
its seal. In this case, process medium enters the holder and exits
through the pressure evacuation holes before the probe is loosened
entirely (thereby informing the personnel that there is still pressure in
the process).
In this case, tighten again the probe until the process is no longer
under pressure. The probe can be then safely removed.
8. MAINTENANCE AND
TROUBLESHOOTING
8.1. Safety instructions
danger
Risk of injury due to high pressure in the installation.
• Stop the circulation of fluid, cut-off the pressure and drain the
pipe before loosening the process connections.
Risk of injury due to high fluid temperatures.
• Use safety gloves to handle the holder.
• Stop the circulation of fluid and drain the pipe before loosening
the process connections.
• Keep all easily flammable fluid or material away from the holder.
Risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention and
safety relating to the use of aggressive fluids.
Warning
Risk of injury due to nonconforming maintenance.
• Maintenance must only be carried out by qualified and skilled
staff with the appropriate tools.
• Ensure that the restart of the installation is controlled after any
interventions.

Maintenance and troubleshooting
8.2. Maintenance
Warning
After repairs or maintenance.
• Ensure that the seal is tight.
• Ensure that all parts are in working order.
note
Special attention must be given in the maintenance plan to the
o-rings. The o-rings used in direct welding holder are consumable
parts, and their life expectancy depends on the conditions in
which they operate. If the temperature frequently exceeds 100°C,
the o-rings must be replaced each time the probe is unscrewed,
because they are easily deformed under conditions of high temperature. If replacement of o-rings according to the plan is not
followed, leakage can occur.
→ Check and replace o-rings as required; always replace at least
once a year.
→ Check that the probe is tightly screwed into the holder. (Weekly
check recommended.)
→ Perform CIP cleaning as required by the type of process.
→ Clean the holder by means of the holes, if contamination with
medium.
→ Thoroughly clean the interior of the holder and the seal pusher if
the probe breaks.
8.3. Cleaning
note
The holder may be damaged by the cleaning product.
• Clean the holder with a cloth dampened with water or a detergent compatible with the materials the cleaning is made of.
• Never use scouring agent containing hard particles.
8.3.1. Cleaning in place (CIP)
If the installation into which the probe is built is being cleaned, the
parts of the holder and the probe that are normally in contact with
the medium (now in contact with the cleaning liquid) can be cleaned
in place, together with the rest of the installation.
8.3.2. Cleaning the interior of the direct
welding holder
If the space between probe and steel frame in the interior of the
holder becomes contaminated, it can be cleaned easily by fitting
cleaning adapters (not supplied by Bürkert) to the (non-threaded)
holes in the wall of the steel frame, and injecting a suitable cleaning
fluid. Alternatively, you can steam-sterilize.

8.3.3. Care of o-rings
• Check the o-rings from time to time.
• When mounting a new o-ring, take care not to damage
the o-ring nut and the o-ring. Otherwise the tightness can
no longer be guaranteed.
O-ring (inside the sleeve)
Sleeve
To replace the front o-ring:
→ Forcefully pull the sleeve from the seal pusher
→ Replace the o-ring
In higher temperature cycles (100 to 140°C) replace the
o-ring each time the probe is unscrewed. This is because
the compression set of EPDM must be considered (DIN
ISO 815, the deviation of the original o-ring form over time,
due to high temperature and pressure).

Spare parts and accessories
9. SPARE PARTS AND
ACCESSORIES
attention
Risk of injury and/or damage caused by the use of unsuitable
parts.
Incorrect accessories and unsuitable spare parts may cause
injuries and damage the holder and the surrounding area.
• Use only original accessories and original spare parts from
Bürkert.
• By default, the direct welding holder is delivered with EPDM
o-rings.
• The adapter with order code 563477 is useful for mounting 120
mm oxygen or conductivity probes. The adapter is screwed onto
the holder and the probe into the adapter. When in place, the end
of the probe is almost flush with the top of the holder.

10. PACKAGING AND TRANSPORT
note
Damage due to transport
Transport may damage an insufficiently protected part.
• Transport the holder in shock-resistant packaging and away
from humidity and dirt.
• Do not expose the holder to temperatures that may exceed the
admissible storage temperature range.
11. STORAGE
note
Poor storage can damage the holder.
• Protect the direct welding holder from cold, wet, direct heat
sources (sun, heaters), soiling, and mechanical disturbance.
• Storage temperature : -30 to 140°C.
