7. Maintenance, Servicing, Cleaning, Repairing
Always open isolating devices gently, never abruptly, since this may
generate sudden pressure surges that may damage the gauge.
Pressure instruments with an electrical output signal require no mainte-
nance and offer a long service life, if handled and operated properly. If the
zero point drifts, it means that the instrument has been overloaded.
Clean the instrument with a moistened cloth. If badly soiled, moisten the
cloth thoroughly with soapy water.
Repairs should be only be carried out by the manufacturer or by appropri-
ately trained staff.
8. Storage
Before the system is stored, all traces of any medium
residue must be removed. This is particularly important,
if the media is a health hazard such as corrosive, toxic,
carcinogenic, radioactice, etc.
Before installation, in order to prevent damage to the pressure instru-
ment, the following points should be observed:
The pressure instrument should be left in its original packaging until
installation.
After taking the instrument out (e.g. for test), reuse the original
packaging material.
The storage temperature should not be less than -40 °C or more
than +90 °C
Avoid the following influences:
Direct sunlight or vicinity to hot objects
Mechanical vibration
Sot, steam, dust, humidity and corrosive gasses
Potentially explosive environment, inflammable atmospheres
