1 Transducer Selection

Selecting the right transducer starts with understanding what and how you want to make your level sensing or fluid identification measurement. TI’s TDC1000 handles ultrasonic TOF measurements and can work with transducers that have a resonance frequency from 30 KHz to 4 MHz. When choosing a transducer, the following questions need to be answered: What frequency? What size? Which Piezo material? Where does it need to be mounted? What temperature range? Each of these questions will be discussed in more detail below.
