6 Maintenance
WARNING
L
Risk of injury if medium escapes
Before every maintenance task make sure that the process pipe or container is empty
‣
and rinsed.
Take all the necessary precautions in time to ensure the operational safety and reliability
of the entire measuring system.
NOTICE
Effects on process and process control
When carrying out any work on the system, take into account possible repercussions
‣
for process control or the process itself.
For your own safety, only use genuine accessories. With genuine parts, the function,
‣
accuracy and reliability are also ensured after maintenance work.
6.1 Servicing the assembly
The assembly must be serviced at regular intervals. The frequency and type of servicing
depend on the medium.
1. Remove buildup on the assembly from time to time.
2. Keep O-rings and sealing surfaces clean.
3. Replace damaged O-rings.
Versehen Sie trockene O-Ringe mit einem dünnen Fettfilm (z.B. Syntheso Glep).
4. Replace damaged parts of the assembly.
Most common types of fouling and suitable cleaning agents
Fouling Suitable cleaning agent
Greases and oils Agents containing surfactants (alkaline agents) or water-soluble
organic solvents (halogen-free, e.g. ethanol)
Limescale deposits, metal hydroxide
buildup, lyophobic biological buildup
Sulfide deposits Mixture of 3% hydrochloric acid and thiocarbamide (commercially
Protein buildup Mixture of 3% hydrochloric acid and pepsin (commercially available)
