| Warning: EMS products are not designed to be used as the sole element in critical systems such as personal safety or life dependency. These systems should always be designed with redundancy. |
| The SONARANGE DUAL ultrasonic
proximity/ranging sensor is a low cost solution to non-contact proximity sensing
applications. As a proximity sensor it gives a much greater sensing range
than is possible with inductive or magnetic sensors. Ultrasonic technology
also provides for sensing non-metallic targets such as wood, cardboard,
glass, minerals, and plastics. The 90degree sensing head allows mounting
in applications requiring limited space.
The SONARANGE DUAL ultrasonic sensor can offer very high resolution in close proximity ranging applications. Using a full 10 bit resolution (A version) over a 1.5" range would offer a theoretical 0.0015" increment. In practice, consideration needs to be given to thermal effects which often frustrate such attempts at this level of precision. The B version can offer an approximate 0.01" level of resolution. |
