WT602 dust meter is an online dust analysis product independently
developed and produced by the company. It adopts the mainstream
laser backscatter measurement technology, and its key components
are all imported. The product is used for continuous monitoring of
particulate matter emission concentrations of various pollution
sources. It can be used with a continuous flue gas monitoring
system (CEMS), or it can be connected to a soot monitoring network
individually or multiple units, sharing a set of data collection
and processing background.
This product is widely used in thermal power generation, iron and
steel metallurgy, petrochemical industry, cement production,
ceramics, waste incineration, etc., various power generation
boilers, industrial kilns, industrial boilers, smoke emission
monitoring and flue gas desulfurization and dust removal project
monitoring and control
1)Laser backward scattering principle can prevent the laser beam
from swinging Then the refractive index is uneven during the
mechanical vibration at uneven temperature.
2)Single-Side installation without optical path alignment.
3)The on-site display can read the dust concentration in the field.
4)After the laser beam is modulated, the system can significantly
improve its anti-interference ability.
5)The device design has been implementing the thinking of" no
tool"on-site installation, to minimize the complexity of field
installation.
6)(4-20)mA standard industrial current output makes the connection
easy.
7)Device overall power consumption is very low at around 3w.
8)Generally, the standard setup parameters are applicable to the
flue wall with a thickness less than 400mm and a diameter greater
than the device stack label size The measuring area can be
customized as required specifically. Users may also adjust the area
under the approval and guidance of the maintenance personnel.
Note: has adopted a 128x64 graphic LCD for display. The LCD
contrast display adjustment can be made through adjusting a
potentiometer on the front panel.
