The single-cell sonic sensor is ideal for tight bends. The compact dimensions of the single-cell sonic sensor make it ideal for use on particularly cramped job sites or winding roads with tight bends. The sensor is also ideal for work requiring high-precision copying of a reference, such as when paving two parallel road surfaces “hot to hot” or “hot to cold”. The single-cell sonic sensor is also useful where major changes in paving height need to be executed within a short time, such as at speed humps.
The single-cell sonic sensor emits just one sound cone, meaning it copies references 1:1, with no averaging. This allows a wide variety of references to be scanned, with the sensor being easily adapted to different job site conditions. It is also quick and easy to install and operate.
This sensor determines the temperature compensation value with the aid of a metal bow located a fixed distance from the sensor. Part of the sound cone reaches this bow, and measures the distance. If the value measured deviates from the actual value, the difference serves as a correction value for the sensor.
