Automotive Glass
Automotive glass production plants around the world are already realizing the benefits of installing a Landscan WCA system.
 
FEATURES AND BENEFITS
Yield enhancements attributable to more consistent product temperature distributions prior to forming to final shape.
Subtracted map displays give immediate post- processed images of the difference between the latest batch and the reference batch.
Database - trending for Quality Assurance, statistical summaries, downstream customers Certificates of Conformity, etc.

An example of a thermal image being used on automotive glass.   WINDSHIELDS
The Landscan or LSP5 sensor head is normally mounted in a rugged housing on the process center-line, above the exit of the heating section.
Product speed is medium to fast; requiring fast scan rates in the range of 25 to 50Hz.

Low-Emissivity coated components for reflection of solar energy
A Landscan sensor head is normally mounted on a Mounting Plate on the process center-line, below the exit of the heating section immediately prior to the shaping dies.
Product speed through the scan plane is medium to fast; requiring fast scan rates in the range of 25 to 50Hz.

     
Side Windows
The Landscan sensor head, sealed in a rugged housing, is mounted on the process center-line and above the exit of the heating section prior to the shaping dies.
Product speed is fast to very fast, requiring faster scan rates in the range of 50 to 100Hz.
Mounting the scanner underneath the process allows the sensor head to scan the uncoated underside of the glass components.
These sensor head installations demand excellent scan alignment and the best quality optics available (small target spot diameters with very low levels of optical aberration) as sighting is normally between a pair of closely-spaced support rollers immediately prior to the shaping dies.

Example data output from an LSC processor   Data Processing
The LSC processor can also be supplied with analogue output cards to facilitate integration of the Landscan derived thermal information with the control system.
Retrofitting 4, 8 or 12 channels of analogue outputs can be easily achieved locally, as and when required with no requirement to return the unit for a factory upgrade.
A TCP/IP Ethernet link is established between the LSC and the Data Server PC, allowing the configuration of operator displays, automatically managed product database (storage by exception if required), subtractive displays, reduced statistical data sets per batch, and simultaneous live and historical displays.
If other remote user groups also require access to the data, this can be achieved via Client Displays (live and historical data) or auto-archiving to a networked file server (historical displays only).

   
LANDSCAN AND LSP systems are increasingly being used to solve temperature measurement problems in a wide variety of industries and applications, some of which are listed below:
 
Hot strip and hot plate mill Rougher, edge heaters, coil box, finishing stands, gauging cold correction, coiler
Beam, billet and sections mill Rail head, beam roughing and finishing, gauging cold correction
Rod/wire mill Pre-coiler, cooling conveyor
Continuous, thin strip and aluminium casting Spray chamber, rougher and induction heater exit, crop shear
Reheat furnace Furnace exit
Welding Turbine shaft and induction pipe welding
Galvanizing Snout, furnace, top roll
Galvanneal Entry dip, top roll
Continuous annealing lines Cooling and heating
Glass Float, forming and toughening
Paper Web and roll
Research and development
