2.2 Probe
e probe consists of a multiple coax cable and an ultrasonic transducer . is is the most
critical part of an RSWA. A malfunctioning or damaged transducer, as well as coax cable,
will make measurements inaccurate or non-existent. Figure 2.2 shows the major parts of the
probe.

2.2.1 Usage
e front face of the transducer is very thin and fragile. Check that there is no dust, grease,
or any other foreign particles between the front face of the probe and the delay line before
mounting the delay. e delay and the coupler are the only replaceable parts on the probe.
Please do not try to disassemble the protective case, take out the matrix transducer, or detach
the cable from the protective case as this will damage the probe beyond repair.
2.2.2 Cleaning and Maintenance
• Clean the front face and the thread of the transducer. If possible, use isopropyl alcohol,
dry using an air jet
• Clean the face of the delay which will be in contact with the front face of the transducer
and the collar using the same technique, dry with an air jet
• For operation, a very thin layer of a standard ultrasonic gel should be applied between
the transducer front face and the delay to provide sufficient acoustical contact
