TRANSDUCER SELECTION
The MX-5 DL is inherently capable of performing measurements on a
wide range of materials, from various metals to glass and plastics.
Different types of material, however, will require the use of different
transducers. Choosing the correct transducer for a job is critical to being
able to easily perform accurate and reliable measurements. The following
paragraphs highlight the important properties of transducers, which should
be considered when selecting a transducer for a specific job.
Generally speaking, the best transducer for a job is one that sends
sufficient ultrasonic energy into the material being measured such that a
strong, stable echo is received by the MX-5 DL. Several factors affect the
strength of ultrasound as it travels. These are outlined below:
•
Initial Signal Strength
The stronger a signal is to begin with, the stronger its return echo
will be. Initial signal strength is largely a factor of the size of the
ultrasound emitter in the transducer. A large emitting area will send
