FTA-D4000 – Dual Detector – Dual-sided Contour Stylus Type

A measuring system has been developed that combines a hybrid dual detector and a dual-sided contour stylus for accurately measuring surface roughness. This system offers improved measurement speed and efficiency, along with automation features to enhance ease of use. It provides a diverse array of features and can be expanded with optional detectors for added functionality.

Product Features 

The ability to hot swap enables the machine to switch between the contour detector and roughness detector without needing to turn off the power.

The tool-less replacement mechanism employs a thumb-turn clamp, allowing for significantly faster switching between detectors.

The stylus drop detection feature identifies and stops the measurement operation if the stylus experiences an abrupt drop.
The collision monitoring system for the magnet arm and detector cover guarantees secure measurements even during fast movements.

Optional accessories for automatic measurement streamline processes from setup to measurement by automating them.

Technical Specifications


Technical Data

The Formtracer Avant D4000 is a comprehensive system that combines a surface roughness and contour detector. This versatile machine allows for effortless swapping of the detector without requiring the machine to be powered off.

Specifically, the FTA-D4000 model is equipped with a dual-sided stylus that enables measurements of inner diameters and the calculation of pitch diameters. 

The dual-sided stylus also offers continuous measurement of both upper and lower surfaces, facilitating faster and easier data analysis of complex features, such as the diameter of an internal screw thread.
