Transducer Problems
Ultrasonic transducers are rugged. However, they are subject to
physical damage due to mishandling and chemical attack. Clamp-
on transducers are also subject to installation variables such as
physical misalignment and faulty coupling to the pipe on which
they are mounted.
Because transducer problems are largely dependent on the type of
transducer used, wetted or clamp-on, the following list of
potential problems is grouped according to transducer type.
Contact GE Panametrics if you cannot solve a transducer-related
problem.
Wetted Transducer Problems
1. LEAKS
Leaks may occur around the transducer and in the fittings of the
flow cell. Repair as you would any other leak. Check the
transducer and cables for damage if the leaking fluid is corrosive.
2. CORROSION DAMAGE
Wetted transducers may be damaged by corrosive fluids if the
transducer material does not match the application. Most often,
corrosion damage occurs at the electrical connector. To check for
damage, remove the transducer from the flow cell. If the wetted
end of the transducer is rough and pitted, the transducer may have
to be replaced. GE Panametrics can supply suitable transducer
materials for most fluids. Contact GE Panametrics for
information on special transducers.
