Coating Weight
Thickness Gauges
CWS-8001

|
Introduction -
The E.S.C.
Resources CWS-8001 non-contact Coating Weight Thickness Gauges provide fast and reliable on line top,
bottom and total thickness measurements and SPC reporting for strip
material. The direct
benefits provided by this measurement are documented compliance with
quality specifications, improved process control and improved production.
The standard system provides disk storage for the SPC information to
eliminate the need to maintain large files of printer paper for long term
record keeping purposes.
Principal of Operation - X-Ray
Fluorescence, this uses the scientific principle that matter will
generate unique energy levels in proportion to it's composition and
coating. As
the material passes between the X-Ray source and detector, variations in
coating cause measurable variations in the amount of x-ray energy
returning to the detector. The gauge is calibrated based on these variations,
and provides a continuous, non-contact, accurate and reliable
measurement of thickness.
System Display - in it's normal
mode of operation, the 17" full color monitor displays actual
coating, deviation, upper and lower tolerance limits, shutter status,
coil footage, and a graphic display of coating for the complete coil.
The coating display changes from green to red if the coating goes
out of tolerance. Additional display screens are provided for I/O status and trouble shooting diagnostics.

Features
 | Easy Installation - no
requirements for cooling. "O" frames typically mount
on two pedestals and require a minimum of cabling. |
| Accuracy - state of the art
high speed electronics and logarithmic linearization performed by
the software assures highly accurate measurements of various
materials while minimizing the hardware requirements. |
| Reliability - this system uses
a modern personal computer, providing a software based system that
reduces the requirement for peripheral hardware. This arrangement
provides a very reliable "platform" for coating measurement and SPC reporting. |
| I/O Capabilities - hardware is
provided to enable communication with a host computer or process
control unit. |
| Automatic Standardization - this provides a fast, accurate
standardization cycle. Up to 10 calibration curves are available to
permit measurement of a wide variety of material types. |
| Diagnostics - system faults
are stored and displayed on demand. A description of the fault and
possible corrective action is also displayed. |
| Upgradeable - this system is
software based, which enables future upgrades to be performed in the
field, via software changes by the customer. |

SPC Reports
| Coating Deviation Plot -
presents a graphic representation of strip coating over the coil
length, in a strip chart fashion. Also indicates location of out of
tolerance material. |
| Coil Report - presents a
histogram of coating distribution, footage, average coating, UCL,
LCL, X Double Bar, R Bar and CPK. |
| Shift Summary Report
- presents a shift summary of
production. |
Note: No optional equipment is
required for disk storage of the Coil Report and the Shift Summary
Report. In addition, both of these reports are customer formattable on
site.
