Abstract
Ultrasonic Transducers of various manufacturers and different types have significant different sensitivity to ultrasonic signals. The difference in sensitivity can lead to over saturation of the signal chain, which introduces measurement inaccuracy.
To adopt the different sensors to the signal chain, also in addition to a variable gain amplifier, the excitation energy and frequency can be dynamically adjusted to the target sensor (i.e. ultrasonic transducer, but not limited to ultrasonic transducers) and measurement environment. An additional solution is to dampen the signal dynamically while maintaining the full excitation pulse energy.
This novel method enables using different sensor types without a hardware driver and acquisition re-design and can potentially expand the range of application environments for the same selected configuration. For Ultrasonic Applications: The same sensor can be used in very low and high attenuation muds without hardware change and could be re-configured at rig-site without additional logistic effort.
