RS485 Chlorine Transmitter For The Measurement Of Disinfectant Chlorine 24V

Brief Introduction

• Free chlorine is the most important disinfectant in water treatment due to its easy handling and strong disinfecting effect.

• The DUC series disinfectant chlorine transmitter DUC2-CL-S-D used with the DRFN sensor helps to achieve safe and efficient disinfection by providing stable and fast measured values.

• The CL controller is a digital universal controller for measuring the concentration of chlorine. Each controller will be pre-installed with a set of embedded software to adapt to different disinfectant sensors.

• This digital chlorine analyzer is connected to the sensor. The sensor uploads the detected data in a special encrypted communication method. The DUC chlorine transmitter can collect high-precision data more stably. It is displayed on the display of the controller in real-time, which is very convenient for users to read.

• The chlorine tester is equipped with a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format.

• The instrument has 2 settable SPST multifunctional relays and 2 high-precision 0/4~20mA current outputs.

Advantages Of The Chlorine Transmitter

1. This disinfectant chlorine analyzer is equipped with RS485 Modbus RTU, RS485 Modbus RTU provides a stable and reliable communication solution suitable for industrial environments, enabling different types of equipment to communicate and control each other, which is beneficial to the integration and management of industrial automation systems.

RS485 allows multiple devices to be connected to the same bus and perform data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible.

RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.

RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.

Modbus RTU is a widely used communication protocol. Its standardization allows devices from different manufacturers to communicate with each other, increasing the interoperability and compatibility of the devices.

2. The DUC disinfectant chlorine transmitter has the functions of clock and historical data recording, which can meet the higher management requirements of users for data.

3. 128*64 large-screen LCD display, Chinese and English language display, rich content, to meet the different needs of users.

4. The shell material of the instrument is reinforced ABS, the shell is strong, corrosion-resistant, and wear-resistant. The overall size of the DUC chlorine gauge is 144*144*120mm, and the user can choose a variety of installation methods such as wall-mounted installation, pipe clamping installation, and panel installation.

5. The controller has a power-off protection configuration, and the parameters can be kept indefinitely.

Applications Of The Chlorine Transmitter

It is applied to online monitoring of chlorine concentration in drinking water and industrial process water disinfection and sterilization process, sewage treatment and circulating cooling water treatment, and can also be used in swimming pools and other places where chlorine concentration needs to be measured.
