The Haze Control is a powerful, microprocessor-based photometric converter. The Haze Control is built off the C4000 design, but has been engineered specifically for high precision haze (turbidity) measurements. The Haze Control converter operates with the optek DTF16 (11°/90° scattered light) and additionally with a sensor AF16, AS16 or AS56 (NIR absorption) e.g. to detect yeast pushes.
The menu-based software is easy to use and configure and is available in German, English, French, Dutch, Spanish, Russian and Portuguese.
The high contrast white display is easy to read and remains configurable. The graphic display can show absorbance, turbidity and concentration in real time, and in any unit of measure such as CU, ppm, EBC, FTU and g/l. These measurements may also be displayed as text, bar graphs or trend values.
The Haze Control software includes adjustable signal damping, 16 linearization tables, and advanced calculation capabilities. An additional feature is the secondary zero for additional offset as well as a slope adjustment. This manual adjustment can be used to compensate for long-term process related disturbances.
An integrated data logger captures vital process information for quality assurance and plant control records. This data is easily transferred to a PC via an RS232 port. The Haze Control series converters provide multiple analog and relay outputs for direct measurement and control. An optional remote card allows process functions such as product switching, ranging, remote zeroing, and hold to be triggered remotely from other process control instruments or systems.
The Haze Control series converters are now available with an optional PROFIBUS® PA interface, which fulfils the Application Profile for Process Automation Version 3.01 with amendment 2. Using cyclic as well as acyclic data traffic the measuring results can be read out together with their corresponding information and product specific settings such as limits of the measuring range and the names of the units.
The converter has eight product selections that can be independently configured. Each product can be setup with four measurement results, three alarm points, up to eight offset + slope sets and up to sixteen linearization tables. These pre-configured products can be changed locally or via access to an individual register via the bus.
