1. Summary
Air Dust Monitor monitors the flying dust concentration for 24 hrs.
After automatically taking in the air including dusts from the air inlet, the dust solid particles
in the air make a transfer of electric charge to the electrode by touching with or passing
near the probe of Air Dust Monitor.
This transfer of electric charge is widely known as triboelectricity or contact charging.
This product will output a 4 to 20mA signal in proportion to the dust amount and some contact
signals, through filtering and amplifying the transfer amount of electric charge.
Important: Dust concentration measurement of triboelectric type Dust Monitor
The triboelectric type Dust Monitor will change an output value in its measurement principle,
corresponding to a variety of environmental factors such as “kind of particle”, “particle
diameter”, “specific gravity”and “flow velocity”.
However, obviously the linearity under a fixed environment will not change.
Regarding the concentration of the triboelectric type dust monitor, as mentioned above, it is
required to consider the effect of physical property change and it is not necessarily corresponding
to the specified concentration.

7-5. Compensation value set
Compensation value can output in a range of 0.1-2.0(double)as compensation coefficient.
In such case as output is too high or too low for actual density when standard coefficient
is 1.0, this function can output nearest density to actual density by multiplying output.
Utilizing this function, output can be compensated as shown hereunder.
Fig. 10. Compensation value
This function is 0.1 in increments of input in the range of 0.1-2.0 (default is 1.0).
If management is only for trend of dust exhaust, you can do without using this function
(=set value 1.0). In case management requires the nearest value to actual density, you seize
actual density such as counter wash pulse time, etc. by manual analysis first and then set
counter wash pulse shown by device very much close to value of manual analysis.
Compensation value 1.0 trend
For actual density,
detect density outputs high.
Compensation value 0.5 trend
For actual density,
Detect density outputs almost
all alike and understood
compensation is effective.
