Single Wavelength Temperature systems

Product News Monday, September 13, 2010: Temperature Controls (Pty) Ltd.

The single-wavelength TempoMatic 4000  and Fiberview 5000 Series Sensors are designed to provide high performance and low maintenance operation in demanding industrial environments. These single-wavelength sensors are used to measure most common materials in general purpose applications. Typical applications are in the glass, steel, electronics, petrochemical, heat treating, paper and plastic industries, as well as many others. As with all single-wavelength designs, the sensors require an unobstructed view of the measured target and a relative constant surface emissivity.

The 4000 and 5000 Series Sensors are intended for use where accuracy and durability are essential to improve product quality, increase productivity and reduce costs. They are made with a versatile high performance design, for optimal process monitoring and control. They also offer a wide selection of temperature ranges, infrared filters, precision optics, and fast response times that can be used to provide accurate and repeatable temperature measurements.

For long time drift free operation, the 4200 and 5200 sensors are patented auto null balancing design that provides greater calibration stability for short wavelength sensors at low temperatures. This unique design is used for applications such as cold rolling steel and low temperature induction heating processes where temperatures can be below 260Uc and the surface has a low or varying emissivity.

For most applications it is recommended to select the sensor with the shortest possible wavelength in order to minimize any effects of changing emissivity. However, unique applications, such as the measurement of visually transparent materials like glass or plastics, require thoughtful wavelength selection. For these applications, Williamson offers a variety of precision narrow band filters.

The TempMatic 4000 Series uses visual (SRL) or laser aiming for accurate alignment to measure very small or distant targets. The FiberView 5000 Series uses durable fiber optic cables to access targets in confined or obstructed areas and to survive excess heat and hostile conditions. Both of these systems are available with a wide variety of field of view options and accessories that can be used to solve difficult applications. The 5000 Series includes a fiber integrity check cavity as well as many unique accessories.
