Product Description

Online WT602B Dust Meter For Steel Manufacture
 Description


Working Principle
WT602B series products use the principle of laser backscatter to complete the measurement of flue dust concentration. The embedded high stable laser signal source passes through the flue and irradiates the smoke particles. The irradiated smoke particles will reflect the laser signal, and the reflected signal intensity changes positively with the smoke concentration. The concentration of flue dust can be calculated by a specific algorithm.

Main Characteristics:
1. Digital signal processing technology, high detection sensitivity and high linearity, eliminate the influence of stray light, and make the measurement more accurate;
2. Optical power adaptive stabilization technology to ensure the stability of the detection light source;
3. Very low zero-point drift design technology, automatic zero point calibration every twenty-four hours;
4. Adaptive full-scale calibration technology, automatic full-scale calibration every twentyfour hours to correct window lens contamination;
5. Anti-harsh environment design technology, extremely low temperature drift;
6. Online calibration, manual zero and span calibration can be achieved without disassembling the instrument;
7. The filter is not affected by sunlight;
8. Integrated structure design, simple and quick installation and maintenance;
9. Provide multiple output interfaces and expandable interface options;
10. Provide the control software User monitor, collect data and control the instrument through the RS485 interface
