Dust removal bag leak detector YX- X7 summary:
With the frequent occurrence of polluted weather all over the country, people attach importance to the environmental air quality and are increasingly strict with the remote emission of industrial dust.
The online dust concentration detector is an instrument for real-time online monitoring of dust concentration, which can be used to monitor the bag damage and leakage of the dust remover and the dust content of each box. It can also be used to monitor dust removal The Conduit , gas pipeline, chimney flue and other dust concentration content; It can accurately monitor the discharge of harmful dust or reduce the loss of useful powder, achieve the purpose of protecting the normal operation of main equipment or reducing excessive loss of products, and can effectively master the operating conditions of bag dust removal boxes and dust discharge of flue pipes.
The online dust concentration detector has high sensitivity, accurate and timely signal, safe and stable operation , easy installation, small maintenance, wide application range (various types of dust, positive and negative pressure systems, large range of dust particle size), sensor can output directly 4 － 20mA reduces the signal in transmission, which is a practical online dust monitoring device for all industries, and can achieve the alarm function of dust concentration exceeding the standard.
II Dust removal bag leak detector widely Application:
Widely used in various industrial applications, including: steel making, power generation, chemical industry, petroleum, building materials processing, coal mining and mining cement , packaging, environmental protection, dust removal equipment and other industries. Typical applications include detection of bag damage of bag type dust remover, or recovery of powdery materials, monitoring of total product delivery, monitoring of boiler smoke emission concentration of gas pipeline, dust removal pipeline or various sizes and fuels, electrostatic precipitator, filter cartridge dust remover, cyclone dust remover, etc., and converter primary dust removal smoke detection system.

IV Dust removal bag leak detector working principle:
The instrument adopts electrostatic measurement technology. In the process of pneumatic conveying, powdery materials will collide and rub, so the powder particles will lose electrons and form positively charged particles and particles. With the change of concentration and powder flow rate, the amount of charge will also change according to certain rules. The charge carried by the dust particles forms an electrostatic field. The size and change of the electrostatic field can be measured by using the electrostatic induction principle. When the airflow containing dust particles in the pipeline passes through a fixed sensor, the weak current generated by the dust particles in motion is transmitted to the sensor Transmitter 。 It is filtered, amplified and processed into a standard output value linearly distributed with the dust content by the transmitter.
