The Sonic Grade Sensor Bail accurately measures the terrain elevation in front of the machine to enable the automatic grade control system to make real-time adjustments to the blade or implement position. The bail positions the transducers at a fixed height above the ground to get consistent and reliable elevation readings.Attributes:• Highly accurate real-time terrain elevation measurement• Provide real-time feedback on the bail's angular position• Reduced wear and tear on machine componentsApplications:The Sonic Grade Sensor Bail allows the machine to continuously adjust the blade or implement height to maintain the desired grade and slope, even as the terrain changes.
