Emissivity enhancer improves bright metal temperature measurement

December 2001 Temperature Measurement

Protea Automation Solutions is offering a Land Infrared emissivity enhancer that improves the accuracy of the Land System 4 and UNO short wavelength thermometers in the temperature measurement of bright metal strip. A further development of the groundbreaking 'Gold Cup' surface pyrometer Land introduced more than 50 years ago, the new emissivity enhancer ensures accurate temperature measurement continuously, and without contact.

It uses a unique nonspherical reflector - currently the subject of a patent application - that gives enhanced emissivity values at a distance of 30 mm from the target surface by maximising the number of reflections between the surface and the reflector.

Intended for use on low emissivity materials, the enhancer is especially suitable for flat, bright rolled finished metals such as stainless and bright annealed steels, aluminium, copper, nickel, brass and many other surfaces normally considered difficult to measure.

The shape of the reflector has been engineered for optimum performance at 30 mm clearance, supplemented by a reflective flange that minimises wide-angle reflections from hot backgrounds.

Suitable for any Land System 4 or UNO thermometer with an SGI or SFI close-up lens, the emissivity enhancer is housed in an accurate alignment jacket to facilitate sighting adjustments, and is supplied complete with an alignment bracket for easy distance and/or angle setting. The accurate alignment jacket also has integral water/air cooling and is designed to accept a standard Land System 4 back cap.
