ATS-K Turbidity Measurement System
Brand: KOBOLD Instruments, Inc
The KOBOLD Model ATS-K is a high precision 2-beam scattered light sensor. It uses the light scattered in the forward direction (11° C) and the transmitted light to measure the particles.
The sensor is manufactured from stainless steel and has been designed for fitting in process pipework.
The process medium is penetrated by a focused beam of light. The light scattered by the particles in the medium is sensed by the receiver optics at an angle of 11° C by four silicon photodiodes. At the same time the unscattered light is absorbed as transmitted light by another photodiode. Unwanted light can thus be compensated for.
Due to the small scattering angle, transmitted light and scattered light practically follow the same path in the medium, which means that product-specific noise variables such as colour or changes in colour of the carrier medium, as well as window soiling can be compensated for. The sensor uses visible (VIS) and near infrared (NIR) light from 400 to 1100 nm.
