In addition, the frame temperature is monitored by implanted
thermocouples with the outputs inputted into the Gauge Controller
algorithms. Using this technique, this Gauge automatically compensates
for any distortions and provides high-resolution thickness measurement,
regardless of the effect of such temperature changes.
Whilst X-Ray and Isotope Thickness Gauges are unable to provide accurate
measurement off both thick and thin plate from one Gauge, plus require
calibration for the various steel alloys, this Gauge operates over a
wide plate thickness range and is totally unaffected by alloy content.
In addition, there are no x-ray or radioactive isotopes that need to be
controlled when in use.
The MDCV83200-2H laser Thickness Gauge operates via a Pentium 3VX Windows
PC Controller mounted in a floor standing cabinet with flat resistive
touch screen and user friendly graphic display. The Converteam HCPI
software also addresses the expansion algorithms for 10 alloys to
provide hot/cold conversion of plate thickness.
The C-Frame is purposely build from heavy steel plate
and I-Beam support to maintain dimensions stability with changing
ambient and high radiant heat emitting from the hot plate as it passes
through the Gauge.
All exposed faces of the Gauge frame are shielded by suspended water
cooled radiators fed from the plant water supply. The rigid C-Frame is
furthermore protected by ceramic board insulation and polished stainless
reflector panels. As added security each Laser chamber is independently
from a closed loop Water Cooler supply.
Changes in the C-Frame throat are automatically compensated for.
Incorporated lasers measure off a Master Plate mounted between the
C-Frame and the line each time the gauge moves from ambush position to
cover the line. This input thereby automatically zeros the Gauge
measured thickness to this master sample. Additional sets of LTMs can be
fitted to measure off Master Samples beside the line to continuously
determine distortions in the C-Frame.
