The Trimble ST400 Sonic Tracker is a reliable, high-precision sonic sensor designed to measure elevation by tracking the height of a machine relative to the ground or a reference surface. Commonly used in 2D machine control systems, the ST400 provides fast, stable height data for dozers, graders, pavers, and other construction machinery, ensuring consistent accuracy across the job site.
Engineered for tough civil, roadworks, and earthmoving environments, the ST400 performs with exceptional reliability in dust, vibration, and changing temperature conditions. It seamlessly integrates with Trimble GCS900 and other 2D control configurations, making it a trusted choice for contractors who depend on accurate elevation control without requiring full 3D GPS.
High-accuracy sonic sensing for real-time elevation measurement
Ideal for 2D machine control grading, trimming, and paving
Fast response and stable reading consistency
Rugged, weather-resistant design for harsh construction environments
Compatible with Trimble GCS900 and 2D machine guidance setups
Improves material usage, grading accuracy, and surface finish quality
