Turbidity Measurement System absorption principle (infrared) Model Typ ATA-K Description of Turbidity Sensor The high precision single-beam turbidity sensor ATA-K measures the degradation of light (in the near infrared range, NIR) passing through the process medium. The sensor has been manufactured from stainless steel and designed for fitting in the process piping. The process medium is penetrated by a suitably focussed, constant beam of light. The intensity of the incoming light is measured by a silicon photodiode and routed to the transmitter as a photoelectric current. The changes of intensity...

Turbidity Measurement System absorption principle (infrared) Model Typ ATT-K Dimensions [mm] ATT-K field housing Ø 5.5 mm Ø (0.22") POWER LAMP FAILURE Operation and Function of Transmitter The change in light intensity is determined in the transmitter ATT-K from the photoelectric current and a measuring signal proportional to the concentration in the process medium is obtained after. Two independently adjustable switch points as well as an analogue output are available for alarm signalling, or control and regulating. An additional relay output (FAILSAFE) signals lamp / system failures. Basic...
