Understrip Temperature Measurement System
For the steelmaker involved in the hot rolling of steel slabs or billets, knowledge of steel temperature is vitally important. Accurate measurement of the steel temperature can be invaluable in determining the final metallurgical properties and quality of the metal.
Land ruggedized fibroptic systems located at different positions under the mill roller table view the target between the rolls and provide continuous accurate measurement, without contact, of the scale-free metal surface.
Understrip Thermometer Features & Benefits
- Simple installation with non critical positioning.
- Quick, simple no-tools probe removal.
- Electronics positioned remotely at a safe distance.
- Minimal services – only clean air supply for purging. No water cooling required.
- The thermometer interfaces with a Landmark Graphic signal processor.
- A range of thermometers are available depending on the temperature range required.
The Understrip Thermometer systems are easy to install and designed for trouble-free operation. A low cost sighting tube/purge unit houses a readily demountable modular fibre optics probe. The associated electronic amplifier unit, located remotely, is linked by a sealed fibre optics light guide.
An air line, connected to the sighting tube, to provide a purged sight path for the thermometer, is the only service required by the thermometer optic head.
The electronics unit is provided with electrical power from the associated System 4 Landmark Graphic signal processor. The processor provides electronic signal treatment of the thermometer output allowing averaging, peak picking or sample and hold outputs and temperature display. An optional serial communications facility gives digital RS232C or RS422A outputs and allows access for system parameter adjustments from a remote computer.
