PRO-100 Sampling probe

The PRO-100 is a heated sampling probe. It is suitable for a variety of working conditions, such as high temperature, high humidity, high dust, high corrosion, etc. Additionally, it offers various probe length to accommodate different size of chimneys or flue pipelines.

The PRO-100 can be used with a variety of sampling tubes, filters, and heating units. It features with high filtration capacity, high filtration precision, strong airtightness, anti-leakage design, and low gas resistance. It also has high temperature control accuracy, temperature overload protection function. It is reliable operation, quick response, and convenient installation and maintenance.

Working principle        

Measuring process: The full-range calibration solenoid valve is closed. The back-blow solenoid valve is closed. The sample gas passes through the heated sampling probe, and heated pipeline before entering the CEMS for

measurement.

Purging process: The full-range calibration solenoid valve is closed. The purging solenoid valve is opened. The compressed air is used to blow and clean the sampling probe to remove the dust. 

Full-range calibration process: The full-range calibration solenoid valve is opened. The purging solenoid valve is closed. The calibration gas passes through the heated pipeline, the full-range calibration tube, and the full-range calibration solenoid valve, then come into the filter element chamber of the sampling probe, and then enters the CEMS system through the sampling pipeline. 

Features                             

•      Heated sampling probe: The probe can effectively avoid the sampling interference or probe blockage caused by high moisture working condition;

•      The probe length can be customized: The probe can be easily disassembled and maintained. It can accommodate chimneys of  different sizes;

•      High precision filtration: The probe has a large filtering area. Integrated filter element unit to prevent the filter element leakage, Easy to disassemble and maintain;

•      High efficiency internal and external purging structure: It can effectively remove the dust, avoid the probe blockage, and reduce the maintenance cost;

•      Full-process calibration: The calibration gas passes through the filter element throughout the process;

•      Assitance acid adding function, and humidity measurement functions are available as an option
