Piezoelectric film (PVDF) ultrasound transmitter and receivers offer unique advantages for air ranging applications. Depending on the applications, resonance frequency and vertical beam directivity of the transmitter and receiver can easily be customized by changing the diameter and length of the PVDF cylinder. The receiver has a very wide horizontal beam angle and it can be reduced by changing the housing design if necessary. Cylindrical 40kHz PVDF receivers exhibit very wide horizontal beam directivity and broad band characteristics. These chacteristics lend unique solutions in many applications such as two-dimensional positioning, digitizer, object detection, and distance measurement. A test board, consisting of snap-in mount holes and test pins, is available for easy evaluation of the 40kHz transmitters. A preamplifier is available for easy evaluation of the 40kHz receivers.
