KWS900 Fiber Optic turbidity sensor
Introduction
Kacise applies fiber technology to the turbidity sensor to make the sensor has better repeatability and stability, not susceptible to ambient light coordination. The sensor’s automatic cleaning brush effectively eliminates air bubbles and reduces the effects of contamination on the measurement. Long-term online use, longer maintenance intervals and better stability.
Feature
- Digital sensor, RS-485 output, support MODBUS
- With automatic cleaning brush, prevent pollution, eliminate air bubbles
- Strong anti-interference ability, no ambient light and chromaticity
- 90° scattered light principle, better fiber technology repeat-ability.
