TF16-EX Dual Channel Scattered Light Sensor |
 |
The model TF16-EX is a precise dual channel, scattered light turbidity sensor. This sensor provides inline control solutions for a variety of industrial processes and is designed especially for hazardous environments. |
The modular sensor consists of a flameproof stainless steel lamp housing and an intrinsically safe detector module. The appropriate converter can be located either in a safe area or in a flameproof or pressurized enclosure directly in the hazardous location. |
The TF16-EX uses light in the VIS and NIR range from 400 to 1100 nm. A precisely defined, constant light beam penetrates the process medium and will be scattered by particles (trace suspended solids, undissolved liquids or
gas bubbles) in the medium. |
The scattered light is detected by photo diodes at an angle of 11° and the unscattered light is detected simultaneously by a reference photo diode. |
This unique dual channel design compensates for disturbances such as background color or color changes of the carrier medium. The sensor can be calibrated in ppm, EBC or FTU and measures extremely low particle sizes and concentrations. |
A special optical sapphire window provides superior resistance to all abrasive and corrosive media. The TF16-EX is available with a broad variety of line sizes, process connections and wetted materials. |
