Topcon Sonic Tracker II 2 9142

Topcon Sonic Tracker II

The Sonic Tracker II measures and controls the elevations of the cylinder. A transducer, located in the bottom of the Sonic Tracker II, generates sound pulses like a speaker and listens for returned echoes like a microphone. The Tracker measures the distance, controlling grade from a physical grade reference, such as a curb, string line, or existing road surface. A temperature bail compensates for rapid air temperature changes. In milling applications, always use a temperature bail.

The Sonic Tracker II attaches to the system through one quick- connect cable and attaches to the machine with a single bolt

Smoothtrac Sonic Averaging System (SAS)

The Smoothtrac Sonic Averaging System (SAS) is an elevation control system that combines multiple Sonic Tracker II's together to calculate an average of the physical reference (Figure 1-6). Each tracker sends its distance measurement to the Control Box which then averages the measurements and sends a correction signal to the cylinder.

The Smoothtrac SAS replaces mechanical skis that drag on the ground. The Smoothtrac connects to the Control Box through the tracker cable.
