The Depth Gauge Rod acts as the moving measuring element inside a depth measuring tool, translating physical contact with a surface into linear motion. When the measuring tip touches a surface or recessed area, the rod travels smoothly along its axis to reflect the depth difference. This movement is transferred directly to the internal reading mechanism, allowing accurate depth indication without delay.Attributes:• Promotes uniform reading behavior across inspection cycles.• Ensures smooth movement during surface engagement.• Allows accurate depth indication through controlled axial motion.Applications: The Depth Gauge Rod is used inside depth measuring tools where it contacts the surface being measured and moves linearly to indicate depth differences through the internal gauge system.
