50mA Blue Green Algae Sensor Digital Automatically Cleaned SS316

Country/Region	china
City & Province	Shaanxi

Product Details

Digital blue-green algae sensor can be directly connected to PLC,DTU water quality monitoring systems without controller

Introduction

The online blue-green algae sensor uses the principle of fluorescence

method, which is more efficient and faster than the traditional manual

counting method, and can be monitored in real time online. The sensor

has better repeatability and stability. With automatic cleaning brush, it can

eliminate air bubbles and reduce the impact of contamination on the

measurement, make the maintenance cycle longer, and maintain excellent

stability for long-term online use It can play an early warning role on algae

reproduction.

Features

★ Digital sensor, RS-485 output, support MODBUS
★ With automatic cleaning brush to prevent contamination and eliminate air bubbles
★ Direct measurement, simpler than traditional manual counting method
★ Continuous online monitoring, real-time control of water quality dynamics

Maintenance methods and common problems Maintenance schedule and method

I. Maintenance schedule

Online blue-green algae sensor with automatic cleaning brush can be automatically cleaned without frequent cleaning.

Maintenance task	Recommended maintenance frequency
Calibrate the sensor (if required by the competent authority)	According to the maintenance schedule required by the competent authority

2. Maintenance method Sensor maintenance

External surface of the sensor: Clean the external surface of the sensor with tap water. If debris remains, wipe it with a moist soft cloth. For some stubborn dirt, you can add some household washing solution to the tap water to clean it.
Check the cable of the sensor: the cable should not be tightened during normal work, otherwise the internal wires of the cable will be easily broken and the sensor will not work properly.

3) Check whether the measurement window of the sensor is dirty and whether the cleaning brush is normal.

Check the sensor's cleaning brush for damage.
18 months of continuous use, need to return to the factory to replace the dynamic sealing device.
