Maintenance
5.1 Safety Considerations
WARNING
Many of the complex chemicals that will be flowed
through the Transducer are either toxic or possibly
pyrophoric (spontaneously ignite in air). Complete
knowledge of the chemical history and appropriate
handling procedures must be followed by skilled
personnel. None of the materials used in the
construction of the Transducer are known to be
hazardous. Refer to the
Transducer’s pressure range
on page 1-3 for the maximum recommended pressures.
5.2 Scheduled [Preventative] Maintenance
There are no components or assemblies that have wear or anticipated failure
characteristics.
5.3 Fuses
A 3.15 amp Type T fuse is located in the Controller. To replace the fuse, contact
Repair Support (refer to
section 1.4.2 on page 1-4 ).
5.4 Cleaning
Procedures appropriate for the chemicals used and compatible with the wetted
materials of the Transducer (SS316L and Inconel® X-750) must be adhered to.
The diaphragms are made from 0.0006 in. (0.0015 cm) Inconel X-750 and
cannot be etched by any cleaner or acid without potential damage.
