MAINTENANCE
8.1. Periodic inspections
Periodic inspections should be carried out in accordance with the standards applicable to the user.
During the inspection it is necessary to check the condition of the head (absence of loosening and
leakage), separating diaphragms (tarnish, corrosion) and the electrical connection (checking
the condition of the cable), as well as the stability of the holder (if used). Check for signs of
mechanical damage in the form of impact marks or dents.
8.1.1. „Zero" check
Every 2 years or in accordance with the user's standards, check the probe's "zero" by pulling the
probe above the liquid mirror and reading the output signal. In case of excessive deviation of
the indication in "zero", the probe should be returned to the manufacturer for correction of
the characteristics.
8.2. Non-periodic inspections
If the probe has been subjected to mechanical damage, pressure overload, hydraulic impulses,
electrical surges, deposits, crystallization of the medium, etching of the diaphragm, or if the probe is
found to be working incorrectly, the device should be inspected. Check the condition of
the diaphragm, clean it, check the electrical functionality and processing characteristics.
If the signal is missing in the transmission line or its value is incorrect, check the power
supply line, the state of connections on terminal strips, connections, etc. Check
the correct value of the supply voltage and the resistance of the load.
8.3. Cleaning/washing
To remove impurities from the external surfaces of the probe wipe it with a cloth dampened
in water.
8.3.1. Diaphragm cleaning
The only possible method of cleaning the probe diaphragms is to dissolve the sludge produced.
Do not remove deposits and impurities from the probe diaphragms, which are formed
during operation, mechanically using tools, since the diaphragms and the probes can
be damaged.
8.4. Spare parts
Parts of the probe that may be worn or damaged and must be replaced: cable and gland seals.
The cable and seals can only be replaced by the manufacturer.
8.5. Repairs
Faulty or non-operational probe shall be provided to the manufacturer or an authorized
representative.
8.6. Returns
In the following cases the, probe should be returned directly to the manufacturer:
-
need for repair;
need for factory calibration or „zero" calibration;
-
-
replacement of improperly selected/shipped probe.
