VAST XT gold active scanning sensor

• Measuring principle

- Active scanning and single-point measuring

- Long styli and high stylus weight

- 500 mm maximum stylus length

- Enables stylus systems up to 500 g

• Application

- In general, any application, including form inspection, curve scanning and free-form surfaces

- Digitization for reverse engineering



Active systems – best possible dynamics

• Similar to scanning systems, this example of a car suspension system shows the difference between an active and passive system.

• The active system assumes control, thus ensuring better control and reaction, as well as high speed.

Constantly lowmeasuring force

Primary axis

Large scanningrange

F

0

The large scanning range minimizes tracking of the primary axis and increases the accuracy and scanning speed.

Measuring force range

Stylus deflection

Compensates for stylus curvature

The electronic suspension delivers a constant measuring force to the surface. The resulting stylus curvature is minimal, constant and easy to compensate.



Passive scanning


The limited scanning range leads to more frequent tracking of the primary axis. This reduces the scanning speed.

Mechanical suspension is deflected. This results in varying measuring forces. The inconsistent stylus bending is difficult to compensate.

Every feature can be reached regardless of the size, accessibility and complexity, or if it is aligned at difficult angles.

Long styli up to 500 mm and 500 g. With the VAST XT gold, every hard-to-reach feature can be measured from any position.

VAST XT gold enables the measurement of the tiniest features with a stylus diameter of 0.5 mm.
