Failure
Possible cause
Procedure
Signal span dropping off/too small
Diaphragm is damaged, e.g. through
impact, abrasive/agressive media;
corrosion of diaphragm/pressure
connector; transmission fluid missing.
Contact the manufacturer and replace
the instrument
Signal span drops off
Moisture present (e.g. at the cable tail) Install the cable correctly
Signal span erratic
Working temperature too high/too low Ensure permissible temperatures as per
the Operating Instructions
Signal span incorrect
Working temperature too high/too low Ensure permissible temperatures as per
the Operating Instructions
Abnormal zero point signal
Medium or ambient temperature too
high/too low
Control the internal temperature of the
instrument within the permissible range;
observe the allowable temperature error
(see Operating Instructions)

Please verify in advance if pressure is being applied (valves/ ball valve etc. open) and if the
right voltage supply and the right type of wiring (2-wire) has been chosen?

If the problem continues, contact WIKA or an authorized agent for assistance. If the level
probe must be returned obtain an RMA (return material authorization) number and shipping
instructions from the place of purchase. Be sure to include detailed information about the
problem. Level probes received by WIKA without a valid RMA number will not be accepted.
Process material certificate (Contamination declaration for returned goods)
Purge / clean dismounted instruments before returning them in order to protect our employees
and the environment from any hazard caused by adherent remaining media.
Service of instruments can only take place safely when a Product Return Form has been
submitted and fully filled-in. This Return Form contains information on all materials with which
the instrument has come into contact, either through installation, test purposes, or cleaning.
You can find the Product Return Form on our internet site (www.wika.de / www.wika.com).
In case of unjustified reclamation we charge the reclamation handling expenses.
*) Make sure that after the assembly the unit is working properly. In case the error continues to exist send in the instrument for
reparation (or replace the unit).
10. Storage, disposal
When storing or disposing of the level probe, take precautions with regard
to remaining media in removed level probes. We recommend cleaning the
level probe properly and carefully. Remaining media in the pressure port
may be hazardous or toxic!
Dispose of instrument components and packaging materials in accordance with the
respective waste treatment and disposal regulations of the region or country to which
the instrument is supplied.
Disposal
Mount the protection cap when storing the pressure transmitter in order to prevent any
damage to the diaphragm.
Storage
Take precautions with regard to remaining media in removed level probes.
Remaining media in the pressure port may be hazardous or toxic!
Remove the level probe from service and mark it to prevent it from being
used again accidentally, if it becomes damaged or unsafe for operation.
Have repairs performed by the manufacturer only.
Do not insert any pointed or hard objects into the pressure port for cleaning to prevent
damage to the diaphragm.
