FILM CONTROL 8100

For thickness measurement on extruded or rolled film in plastics and rubber, the
series FILMCONTROL 8100 is available with various measurement technologies. It
is based on the principle of combination sensor systems and can be adapted most
easily. Consequently, numerous types of materials and surfaces can be measured.
All the methods feature high dynamic response and spatial resolution. In contrast to
radiation measurement methods using isotopes and X-ray radiation,
FILMCONTROL is better environmentally and offers substantially more conomical
process costs.

The series 8100 is designed for
Extruded and rolled film
- Unvulcanized rubber
- Foam materials

Other system properties:
- Dynamic measurement with high accuracy and high spatial resolution.
- Temperature stability through online calibration
- Environmentally friendly measurement techniques,
no use of isotope or X-ray radiation
- Extensive analysis software for running under Windows

Combination sensor system EO
(eddy-current - optical sensor)
Field of application:
Multi-layer (coextruded) film
The combination sensor system EO 14 acquires the top of the
film with a laser micrometer. Simultaneously, the eddy current
sensor measures the surface of the roller and, by implication,
the bottom of the material. The thickness of the measured
material is determined by taking the difference between the signals.

Combination sensor system EC
(eddy-current - capacitive sensor)
Field of application:
Homogeneous, single-layer film
The combination sensor system EC 5 consists of a capacitive
and an eddy current displacement sensor which are accommodated
together on one axis in a sensor housing. The eddy
current sensor measures the distance to the measurement roller
and therefore compensates for changes in the mechanical
measurement setup, whereas the capacitive displacement
sensor acquires the material thickness without making contact.

Combination sensor system ET
(eddy-current - triangulation sensor)
Field of application:
Foam material
With the combination sensor system ET 12 a precision ceramic
ball with a low load pressure is passed over the material. The
ball is acquired with the triangulation sensor which then
indirectly measures the surface contour of the material. The
eddy current sensor in turn measures the top of the roller.
