PTU8011 Inline Turbidity Sensor, Turbidity Sensors, Water Turbidity Sensor for Industry/Lab
Introduction
The PTU8011 Turbidity Sensor is a high-performance optical device designed for continuous monitoring of water turbidity. It operates based on the principle of light scattering and is equipped with advanced photodetectors for highly accurate turbidity readings. The sensor is capable of measuring turbidity in a wide range of concentrations (0-1000 NTU), making it ideal for a variety of applications, from environmental monitoring to industrial process control.
Built with durability in mind, the PTU8011 turbidit sensor is designed to withstand harsh environments and deliver consistent performance. The sensor offers easy integration with existing monitoring systems and features long-term stability, reducing maintenance and downtime.
Working principle
The PTU8011 Turbidity Sensor operates based on the principle of nephelometric turbidity measurement, where suspended particles in the water scatter light. The sensor emits light into the water sample, and the amount of scattered light is measured by a photodetector at a fixed angle (typically 90°). The scattered light correlates with the concentration of suspended particles in the water, which is then converted into a turbidity reading in NTU (Nephelometric Turbidity Units).
The sensor is designed for high sensitivity and fast response, making it ideal for real-time monitoring in dynamic environments. The optical system and advanced electronics ensure that measurements are highly accurate, providing users with reliable data for managing water quality.
