Efficiently identify product performance


The ultrasonic transducers we produce usually have laser-printed characters, such as 40T/40R in the picture above, of course, it may be 25T/25R, or other labels. Let us briefly explain the meaning of these characters.

The number 40 represents the frequency of the ultrasonic transducer, that is, the frequency of this ultrasonic transducer is 40khz, then the number 25 or 23 represents the frequency of 25Khz and 23Khz.

The letter T stands for transmitter and R stands for receiver.
