Operating Instructions
Description
The transmitted light and scattered light signals generated in the sensor are amplified in the KOBOLD transmitter ATT-K to produce a weighted ratio. The measured variable thus created is proportional to the total volume of particles in the carrier medium. Two independently adjustable switch points as well as a mA output are available for alarm signalling, or control and regulating.
An additional relay output (FAIL-SAFE) signals lamp or system failures. Basic system calibration is carried out as standard in ppm DE (mg infusorial earth / L water). The device may also be calibrated to FTU (Formazin Turbidity Standard) or to EBC (European Brewery Convention) if required.
