CEMS flue gas emission online monitoring system:It refers to a device that continuously monitors the concentration and total emissions of gaseous pollutants and particulate matter emitted by atmospheric pollution sources, and transmits the information in real time to the main pipeline department.

Process Introduction:Before entering the analytical instrument, smoke or gas needs to go through heat tracing pipelines, dehumidification, condensation and other steps, all of which require constant temperature control. The set temperature is 120-160 ℃, and one device has 3-4 temperature control meters. Conventional use of thermal resistors or thermocouples to control SSR solid-state relays requires remote transmission of temperature through 4-20mA transmission to monitor real-time temperature on the upper computer.

Defects in the original temperature control scheme:Previously, major system equipment manufacturers used 48mmx48mm temperature controllers for temperature control. The temperature was transmitted through a 4-20mA transmission output, and the data was remotely transmitted to the upper computer for the Environmental Protection Bureau to monitor temperature data at any time. An online monitoring system requires 3-4 48mmx48mm temperature controllers, and the upper computer needs to be matched with the same number of 4-20mA receiving and acquisition ports for long-distance transmission, with weak signals and single functions.

The value that Yudian's temperature control solution brings to customers:Through communication with the customer's technical department, we recommend the AI-7348 and AI-7048 multi-channel temperature controllers. This product integrates four temperature control functions and has long-distance transmission through 485 communication. It can not only record measurement values in real time, but also read alarm status and other data, and set preset values.

Adopting guide rail installation, with a width of only 22.5mm, it reduces the number of temperature controllers used, does not occupy space, effectively reduces costs, and increases collection function and efficiency.

Customer Comment:The temperature control solution recommended by Yudian has been widely recognized in our environmental protection industry, and Yudian's APID algorithm, most online monitoring systems, and temperature control modules can achieve automatic and stable control without the need for debugging after power on. The modular assembly method of Yudian has a fast delivery time, and normal orders can be shipped within 2 working days. Customers do not need to stock up in large quantities or have funds temporarily.
