optek - Model TF56-N -Dual Channel Turbidity Sensor
The TF56-N sensor is an inline real-time device designed to measure light absorbance at 11° caused by interaction with process turbidity. As an NIR light beam is passed through a dynamic process stream, the sensor simultaneously measures the amount of light scattered at 11° and the remaining amount of un-scattered light at 0°.
The TF56-N is a precision scattered light turbidity sensor, which is designed for inline operation. Light scattered from particles (trace suspended solids, undissolved liquids or gas bubbles) in the medium is detected by four hermetically sealed silicon photodiodes at an angle of 11°. At the same time, the direct light is detected by a reference photodiode. This unique dual channel design compensates for disturbances of the carrier medium. The sensor can be calibrated in ppm (DE), EBC or FTU and measures extremely low particle sizes and concentrations.
