KWS-3000 Online Residual Chlorine sensor
Introduction
It is used for continuous monitoring of residual chlorine content in aqueous solution in drinking water treatment plants, canning plants, drinking water distribution networks, swimming pools, cooling circulating water, water quality treatment engineering and so on.
Dimension
Installation and Electrical Connection
Installation
Using the matching circulation pool installation, the electrode and the circulation pool are installed closely to ensure that the electrode measurement part is placed in the area near the inlet of the circulation pool, and the flow rate should not be aligned to the outlet as far as possible to ensure the steady flow rate. It is suggested that the flow rate should be controlled at 30 ≤ 60L / h to ensure the accuracy of the test.
Wiring
Red wire-power cord（12～24VDC）
Black wire-ground wire（GND）
Blue Line-485A
White Line-485B
Bare wire-shield line
After the wiring is completed, it should be carefully checked to avoid the wrong connection before the power is turned on.
Cable specification: Considering that the cable is immersed in water (including sea water) or exposed to air for a long time, the cable has a certain corrosion resistance. The Φ 6 mm, joint of cable outer diameter needs waterproof treatment.
