> The DMS Ultrasonic Acoustic Wave-Guide TransducerŠ
A transducer (or sensor) is a device that can convert motion, displacement, pressure, temperature, etc., into an electrical signal. Although the sensor industry offers an impressive array of off-the-shelf measurement transducers, when it comes to racing, the requirements for the transducer become very hard to satisfy.
DMS needed a transducer that would be able to make long measurements, withstand the brutally harsh environment of professional motocross racing, be easy to install, and be inexpensive to replace if broken. As it turned out, no such transducer existed. It needed to be invented.
To meet the criteria, the Ultrasonic Acoustic Wave-Guide Transducer (UAWG) was developed and patented. This is a rugged measurement device that uses sound waves to measure distance (like sonar).
The Transducer Head is a small, lightweight billet aluminum assembly. It transmits high frequency sound waves down the inside of the telescoping wave-guide tube. The sound wave bounces off the top of a piston mounted to the lower tube and returns to the transducer (like sonar). The distance is calculated within 0.5 mm, 240 times per second.
