INTRODUCTION
These unique sensors have been designed to measure Turbidity based on nephelometric method (ISO 7027 – EN 27027). The sensors are available for submersible and in-pipe installations.
The measuring system consists of:
- Infrared light source
- 90 degree scattered light detector
- Detector of the clean lens status
- 2-wire 4/20 mA analog output
- Modbus Output
- Nozzle for the autoclean by external pressured air (TU 8325)
Principle of operation
The Turbidity follows the nephelometric method (ISO 7027 – EN 27027). A light beam is sent to the sample through an optical lens. The 90 degree scattered light by suspended particle is collected by the sensor through a second lens and it is converted in an electric signal proportional to the Turbidity of the sample. The probe uses an infrared light and the measuring is not affected by the color of the sample.
