How To Tell If Your Transducer Is Bad (Quick Checklist)
https://sportfishingbuddy.com/how-to-tell-if-transducer-is-bad/
The first thing you can do to test if your transducer is working is to turn it on and touch its surface. You should be able to feel the sound pulses as vibrations, and often you can also hear them as clicking sounds. Next, in order to test its performance, do this:
Ultrasonic Transducers Technical Notes
http://ru.twn-technology.com/Download/Olympus/Olympus%20transducers%20EN.pdf
Transducer waveform and spectrum analysis is done according to test conditions and definitions of ASTM E1065. Typical units are MHz for frequency analysis, microseconds for waveform analysis, and dB down from peak amplitude. Figure (4) illustrates waveform duration at the -14 dB level or 20% amplitude of peak.
Nondestructive Evaluation Techniques : Ultrasound
https://www.nde-ed.org/NDETechniques/Ultrasonics/immersion.xhtml
In immersion testing, the transducer is placed in the water, above the test object, and a beam of sound is projected. The graph of peaks using the immersion method is slightly different. Between the initial pulse and the back wall peaks there will be an additional peak caused by the sound wave going from the water to the test material.

Along the lines of lab equipment. To test some basic functionality, I can "listen" for clicks from the transducer. Also, if it wasn't permanently mounted, I could also hold it upright, place some sand or salt on it, activate it, and look for any patterns that my form on the surface.
Testing Pressure Transducers - Omega Engineering
https://www.omega.com/en-us/resources/testing-pressure-transducer
Testing pressure transducer before installation is important. It allows you to determine any faults in the system. If you install a faulty pressure transducer, you are likely to get false pressure data, which can lead to undesirable results. Testing pressure transducers at certain intervals is also a good practice to ensure that it is working ...
UT Immersion Testing - World Of NDT
https://worldofndt.com/ut-immersion-testing/
Wheel Transducers UT immersion Technique: The wheel transducer technique is a variant of the UT immersion method in that the sound beam is projected through a water filled tire into the test object. The transducer, mounted in the wheel axle, is held in a fixed position while the wheel and the tire rotate freely.
