1.4 Operational safety
Before commissioning the entire measuring point, make sure all the connections are
‣
correct. Ensure that electrical cables and hose connections are not damaged.
‣ Do not operate damaged products, and secure them against unintentional
commissioning. Mark the damaged product as defective.
‣ If faults cannot be rectified, the products must be taken out of service and secured against
unintentional commissioning.
1.5 Product safety

3.2.2 Installing the assembly in the process
If medium escapes, this poses a risk of injury from high pressure, high temperature or
contact with chemicals.
‣ Wear protective clothing, gloves and goggles.
‣ Only mount the assembly on empty and unpressurized tanks or pipes.
1. Make sure the seal between the assembly and process adapter sealing surface is seated
and positioned correctly.
2. Secure the assembly to the tank or pipe with the process connection. In the case of
versions A, B, M and N, only tighten the union nut finger-tight.
3. If you are not installing a sensor immediately, install the dummy plug instead of the
sensor.

3.2.3 Sensor installation
If medium escapes, this poses a risk of injury from high pressure, high temperature or
contact with chemicals.
‣ Wear protective clothing, gloves and goggles.
‣ Only mount the sensor on empty and unpressurized tanks or pipes.
1. Remove the protection cap on the sensor.
Make sure that the O-ring and thrust
collar ( å 7, item 1) are present.
2. Immerse the sensor shaft in water. This
makes installation easier.
3. Remove the dummy plug.
4. Screw in the sensor:
– first screw it in finger-tight,
– then tighten it by approx. ¼ rotation
with a socket wrench (17 mm AF).
5. Connect the measuring cable to the
sensor.
6. For KCl sensors: connect the KCl supply
line.

3.3 Post-installation check
• After installation, check all the connections to ensure they are secure and leak-tight.
• Ensure that the hoses can only be removed by force.
• Check all hoses for damage.

CAUTION

4 Maintenance
Risk of injury if medium escapes!
‣ Before performing any maintenance task, make sure that the process pipe is
unpressurized, empty and rinsed.
4.1 Cleaning the assembly
The assembly must be cleaned regularly to ensure stable and reliable sampling. The
frequency and intensity of the cleaning process depend on the medium.
• Remove light dirt using suitable cleaning solutions (see the "Cleaning agent" section).
• Use a soft brush and a suitable cleaning agent for stubborn dirt.
• For very persistent dirt, soak the parts in a cleaning solution and then clean the parts with
a brush.
A typical cleaning interval for drinking water would be 6 months, for instance.
You can also clean the assembly in-line (CIP).
You can also sterilize the assembly in-line (SIP) if the sensor is SIP-enabled and the assembly
is made from stainless steel or Alloy C22.
The assembly can also be autoclaved with the appropriate sensor.
4.2 Cleaning agent
The choice of cleaning agent depends on the degree and type of fouling. The most common
fouling and the suitable cleaning agents are provided in the following table.
Type of fouling Cleaning agent
Greases and oils Agents containing surfactants (alkaline) or water-soluble
organic solvents (halogen-free, e.g. ethanol)
Lime deposits, metal hydroxide buildup,
lyophobic biological buildup
Sulfide deposits Mixture of 3% hydrochloric acid and thiocarbamide
Proteins deposits Mixture of 3% hydrochloric acid and pepsin (commercially
Fibers, suspended substances Pressurized water, possibly surface-active agent
Light biological deposits Pressurized water
Approx. 3% hydrochloric acid
(commercially available)
available)
Health risk due to solvents
‣ Do not use acetone or organic solvents containing halogen. These solvents can destroy
plastic parts of the sensor and some are also suspected of being carcinogenic (e.g.
chloroform).

4.3 Leak monitoring (optional)
Check for leaks (visual inspection) at
regular intervals. If medium has escaped at
the monitoring hole, the molded seal must
be replaced.
a0019977
Fig. 8: Leakage monitoring
1 Leak monitoring
4.4 Replacing the seals
To replace the seals in the assembly, you must interrupt the process and remove the entire
assembly.
Residual medium and high temperatures can cause injury
‣ Protect yourself against residual medium and high temperatures when handling parts in
contact with the medium. Wear protective goggles and safety gloves.
Clean the assembly before replacing the seals (see the "Cleaning the assembly" section).
Preparatory steps:
1. Interrupt the process. Watch out for residual medium, residual pressure and high
temperatures.
2. Remove the sensor.
3. Detach the assembly completely from the process connection.
4. Clean the assembly (see the "Cleaning the assembly" section).

5.1 Replacing damaged parts
Incorrect repair work can pose a hazard
‣ Damage to the assembly which impacts the pressure safety must only be repaired by
authorized technical personnel.
‣ After every repair and maintenance activity, suitable measures must be taken to check
the assembly and ensure it shows no signs of leaking. Afterwards, the assembly must
again meet the specifications in the technical data.
Replace all other damaged components immediately.
