THE KAMAN ADVANTAGE

The Kaman KµDA measuring is easy to use, configure and re-calibrate in the field with its Windows-based software. It is rugged. The sensor can withstand pressures up to 20,000 psi and temperatures to 400°F. It can be used on-line. Kaman's sensor measures the thickness of the plastic as the part is being molded, so defects are discovered before the product is ejected and packaged. It is noncontact. Using eddy current technology, the sensor can measure the position of the inner core through the plastic without ever touching it. The result is an extremely reliable system with no moving parts. It gives accurate results. The KµDA actively compensates for the temperature shifts of a molding environment resulting in accurate readiness between start-up and run conditions.

GOAL

* Measure the wall thickness of a plastic part as it is being molded.

* Keep the wall thickness (or part dimension) uniform.

* Minimize the plastic used to avoid excess waste.

* Make measurements in a harsh environment.

SOLUTION

KµDA Digital Signal Conditioner and Custom Sensor How does the system work? The sensor is embedded and sealed into the outer mold. To determine thickness, the sensor measures the gap between the mold and the core for comparison with the finished part specification. The KµDA digital signal conditioner captures thickness data on every part, providing 100% quality control. Result: Optimal wall thickness is attained and defective parts are identified.

The KµDA Digital Signal Conditioner can activate an alarm if parts are out-of-spec. It can displa trends related to part quality with changes in pressure, temperature or other parameter changes. It collects SPC and other quality data. It will interface to a plant network via RS232 or RS485.
