4.2 Particulates Monitoring Sub-System
Fig 4-5 LDM-100 Laser Dust Meter
The LDM-100 laser dust meter is mainly composed of emitter unit and reflector unit, as
shown in Fig 4-5. The emitter unit drives the laser generator to emit the laser. When the laser
passes through the tested environment, the laser beam will be reflexed by the reflector unit to the
sensor of emitter unit for photoelectric conversion and MCU analysis to calculate out the
measurement result.
The LDM-100 laser dust meter is based on laser transmission testing technology and featured
of advantages like fast response and high testing sensitivity. Its testing is based on in-situ
measurement mode. The emitter unit and reflector unit of LDM-100 laser dust meter are directly
installed on the stack by the connection unit. Please refer to the
LDM-100 User Manual
for more
information.
4.3 Gas Parameter Monitoring Sub-System
The gas parameters include temperature, pressure, flow rate and humidity. The humidity of
gas is measured by the humidity measurement module. Other parameters can be measured by two
types of solutions: using separate transmitters to measure the temperature, pressure and pressure
difference or using TPF-100 integrated transmitter.
