Dust concentration detector widely used in various industries, including: steel, power generation, petroleum, chemical, *, building materials processing, mining and mining, cement manufacturing and packaging industries. Typical uses include baghouse filter bag breakage detection, or powdered material recovery, product total transport monitoring, or a variety of sizes, a variety of fuel boiler soot emission concentration monitoring; plant dedusting pipes dust monitor, dust bag leak detection instrument, wooden products factory dust concentrations pipeline inspection, pipeline coal dust concentration detector, fan pipe-line dust monitor, line pipe dust concentration alarm, dust detector, etc.; Overview: This instrument is the result of an induced electrostatic charge fixed probe volume. Dust particles with electrostatic charge induced in the probe, the probe signal amplification and transmission into the monitoring and control system. The size of the electrostatic charge of dust particles than the flow rate. Tech electronics of the system converted into this part of the charge control signal output, start alert excessive emissions of dust, dust particles continuously recorded for both the total amount or concentration. Device provides the world's latest technology AC-coupled. This is the most accurate and stable modern monitoring techniques, particularly suitable for continuous discharge records and data accumulation. The monitoring system works through the use of the dust particles generated around the probe to confirm the charge sensing line emission of dust particles (mg / sec) or emission concentration (mg/m3). Relatively stable combustion conditions in the case (i.e., the same point of discharge, the flow rate, temperature, pressure, humidity, and dust particles are not very great change in the nature, is less than ± 90% change), the system is determined by direct calibration could also be used for online monitoring of emission concentrations (unit = mg/M3). In flowing powders, granules and particles, particles and the wall, due to friction between the particles and the bag, collision electrostatic charge, the formation of electrostatic field, the electrostatic field changes that reflect the dust content changes. Leak is by measuring the change in the electrostatic field, to determine the bag filter system is running correctly. When the bag is broken, the dust content in the pipeline phase flow increases, while the electrostatic field strength increases. Technical parameters: Operating ambient temperature -20 ℃ ~ 60 ℃ (electronic components) Operating humidity 90% non-condensing Maximum continuous operating ambient vibration shock volume, in any direction, at any frequency: rms value 2g (20m/s2) Operating Environment electromagnetic field at 50 Hz maximum value = 60A / m (equivalent to a 1 m × 1 米 have 50AT square solenoid coil magnetic field) operating environmental protection: IP66/NEMA4 aluminum alloy shell, suitable for the installation of non-corrosive environments , stainless steel probe pipeline gas pressure -0.1 - 1MPa pipeline gas velocity 1m / s ~ 30m / s pipeline gas temperature -50 ℃ ~ 450 ℃ pipe diameter 0.1 meters to 4 meters standard probe probe structure is M6, length 160 mm 316 stainless steel rod. Dust particle size range of nominal 0.1μM ~ 200 μM, outside the scope of the nominal signal characteristics but still be able to receive a little bit different. Zero drift (time) is less than 1% of range per year. Zero drift (temperature) within the specified temperature range, less than 1% of range. Full Scale Drift (time) is less than 1% of range per year span drift (temperature) within the specified temperature range, less than 1% of range. Line Stability System All components are made of high stability electronic assemblies. Noise resistance all 50 or 60 Hz and harmonics are in the audio signal is filtered out before receiving full range 0-9/12/25/50/100/200/400/800/1000 mg/M3 transmitter output wire 4 - 20mA (built-isolator, tamper-proof) Transmitter Power Supply 15V - 32VDC works: dust concentration detector using the most reliable electrostatic measurement techniques. When the pipeline contains dust particles flow through a fixed sensor, the dust particles generated in motion weak current collected by the sensor and transmitted to the transmitter. The transmitter is filtered, amplified, and processed into a linear relationship with the dust content of the standard output. Features Advantages: 1, using the most advanced and practical technology - Patent Improved AC-coupled technology, the dust detection sensitivity, linearity, dust contaminated with the probe does not affect the measurement sensitivity, maintenance free cleaning; 2, the standard two-wire 4 -20mA current output, anti-interference ability, easy long-distance signal transmission, the signal transmission line no special requirements, the output current is a linear relationship with the concentration of dust, PLC data to facilitate subsequent processing. 3, the installation uses exactly the same two-wire pressure transmitter, field engineering and technical personnel to the proper use without any special, easy installation and reliable operation. 4, junction box built-in integrated transmitter 4-20mA current output and electrical isolation between the dust sensing probe, secure transmission of the signals.
