GOAL

* Regulating the thickness of a nonconductive fiber web across its width and length (rubber, paper, dough, plastic, particle board, etc.).

* Maintaining a precise material thickness (±0.001 inch).

* Making measurements in the presence of environmental contaminants.

SOLUTION

Kaman's KDM-8000 measuring system How does the system work? Web thickness is controlled by the position of two calender rollers. Kaman's single-channel sensor is mounted on a shoe that slides across the web as it exits the rollers. The sensor looks through the nonconductive web to measure the distance to a metal backing. Kaman's system provides a DC analog signal - directly proportional to the web thickness.

Result: Improved web quality and reduced process costs.

THE KAMAN ADVANTAGE

Why use the Kaman KDM-8000 measuring system? It is noncontact. Using eddy current technology, the sensor can measure position without ever touching the target. The result is an extremely reliable system with no moving parts. It can be used on-line. The sensor measures the web thickness as the material exits the rollers. A set point can be triggered to warn when out-of-tolerance conditions are reached. It is rugged. Kaman's system components - the sensors and a NEMA-12 box used to house the signal conditioning electronics - are unaffected by environmental contaminants. It offers versatility. The KDM-8000 contact measurement is equally effective for particle board and plastics. The KDM-8000 is accurate. The system passively compensates for the temperature shifts of the process environment.
