TURBImat-HC (NIR-Absorption)

The Model TURBImat-HC inline turbidity sensor, featuring a rod-style probe design, measures the NIR absorption of particles and other turbidity-causing substances in liquids. The probe can be configured as an immersion sensor or as a rod-style sensor for installation in a pipeline; in the latter case, mounting is achieved via a ball valve or a flange on the probe shaft.

Common Applications

Paper Industry

The turbidity sensor operates on the principle of NIR absorption to measure suspended solids in liquids. The optical system is equipped with near-infrared LED light sources and a high-precision photodiode detector. Measurement in the near-infrared range provides accurate and reliable results that are unaffected by changes in product color. The probe windows can be cleaned during operation using integrated cleaning nozzles, eliminating the need for wear-prone mechanical wipers or other moving cleaning components.

The inline turbidity sensor TURBImat-HC operates using the NIR absorption principle at a typical wavelength of 880 nm, delivering highly accurate, color-independent measurements with excellent repeatability. Variable optical path lengths allow the sensor to be adapted to a wide range of concentration levels, from low turbidity to high suspended solids content. Freely configurable scaling in units such as ppm, mg/L, or percent ensures seamless integration into industrial processes, while robust materials such as stainless steel and sapphire provide outstanding durability and long service life.

The sensor offers low maintenance requirements, extended calibration intervals, and integrated nozzle cleaning without wear-prone mechanical components. Installation via ball valve or flange allows the sensor to be inserted or removed without interrupting the process, making the TURBImat-HC an ideal solution for demanding applications in pipelines, tanks, and open process systems.
