TF16-EX-N Dual Channel Scattered Light Sensor |
 |
The model TF16-EX-N 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. |
High particle concentrations can be monitored color independent at the direct light detector. The TF16-N uses light in the near infrared (NIR) range from 730 to 970 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. |
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-N is available with a broad variety of line sizes, process connections and wetted materials. |
