A Fibre-optic Temperature Measurement System Ametek Understrip

Descriptions

AMETEK Land’s application-specific solution for temperature measurements in the hot rolling of flat steel products, the Understrip is a rugged, accurate system designed to take measurements from the underside of the steel. This avoids any effects from surface water or minor scale that may exist on the top side. In addition for lower temperature, short wavelength measurements close to the coiler the underside design avoids possible ambient lighting interference. USTS are commonly custom designed for each mill and location to accommodate the variety of roll table designs that exist.  

Easy to install and designed to provide trouble-free operation, the system consists of a low-cost sighting tube/purge unit housing a demountable fibre-optic probe linked to an electronic amplifier unit by a sealed light guide.

The sensor electronics are positioned remotely. Two types of USTS are available, dependent of the needs of the mill. The portable version can be slid under the line easily, and if necessary removed and slid under the line at another monitoring position. This makes for a very useful process analysis tool. A permanent mount version is also available.  You can choose temperature sensors from the SPOT, System 4 or UNO pyrometer families.

Developed specifically for use in the steel industry, the Understrip system is ideal for steelmakers involved in the hot rolling of flat steel products, where accurate temperature measurements determine the final metallurgical properties of the metal.

DESIGNED FOR APPLICATION CONDITIONS

Being application-specific, the system is built for steel mill conditions. The readily demountable probe fits various positions under the mill roller, while the electronics are remotely located to avoid damage and reduce maintenance requirements.

MINIMAL SERVICES

The Understrip system only needs a clean air supply for purging the thermometer sight path – no water cooling is required. Rugged and dependable – systems operate continuously for years with little or no maintenance.
