１．OUTLINE
An electric charge is generated when solid particles in the gas passes through the probe of
the dust monitor on the duct or pipe.
This electric charge is known as frictional static electricity or contact electrification.
The size of the electric charge can be calculated by the following equation and be regarded
as the value of the electrical current and is in proportion to the amount of dust.
Ｋ ・ Ｍ ・ Ｖ
ｂ
Ｉ＝ ─────────────
ｄ
Ｉ ＝ Current signal
Ｖ ＝ Flow velocity
Ｋ ＝ Constant depending on a particle
ｂ ＝ Coefficient
Ｍ ＝ Particle mass
ｄ ＝ Diameter of a particle
After the signal for the current is filtered and amplified, an instrumentation signal and
a contact signal between 4mA to 20mA in proportion to the amount of dust are sent.

６．STARTUP
6-1．Warming-up
The Dust Monitor needs to warm up for approximately one hour after the power supply
is turned on.
6-2．Measuring Range
After warming up, set the optimum measuring range. First, set the Range Switch to
“1～4” if the flow speed is constant, the operation of the filter is normal,
and the dust is the environmental conditions are normal.
When the watch of a smaller change is necessary, a detailed change can be observed
by setting the range between “5～9”.
(However, it becomes easy for the overrange to do when the density is high. )
4mA(0%) 20mA(100%) 4mA(0%) 20mA(100%)
Measuring range1 ： 0.1 ～ 1000mg/m
3
Measuring range6 ： 0.1 ～ 20mg/m
3
Measuring range2 ： 0.1 ～ 500mg/m
3
Measuring range7 ： 0.1 ～ 10mg/m
3
Measuring range3 ： 0.1 ～ 200mg/m
3
Measuring range8 ： 0.1 ～ 5mg/m
3
Measuring range4 ： 0.1 ～ 100mg/m
3
Measuring range9 ： 0.1 ～ 2mg/m
3
Measuring range5 ： 0.1 ～ 50mg/m
3
Use the Range Switch described in section 5. OPERATION METHOD to set the measuring range.
The numbers on the switch correspond to the ranges.
Attention: The rotate switch has numbers from 0 to 9 on the switch, but only 1 to 9 are used.
Number 0 is the Maintenance mode .
(Refer to 10. MAINTENANCE MODE .)
The Dust Monitor uses “talc” as standard powder and is designed so that 20mA
will be output at 1000 mg/m
3
, which is the maximum range in a 10 m/s flow speed environment.
Each range is designed so that 20mA will be output at the maximum value of each range.
The linearity of the output at 1000 mg/m
3
will not change.
【Reference: Talc】
Talc is finely pulverized ore and gray-white, smooth inorganic powder.
Talc is chemically called hydro-silica magnesium [Mg3Si4010 (OH)] of which main components
are; approx. 60% of SiO2, approx. 30% of MgO, and 4.88 % of crystal water.
Its physical characteristics are; true specific gravity of 2.7 to 2.8, the hardest among
the inorganic minerals (Mohs’ hardness 1), excellent in heat resistance, and
chemically stable.
6-3．Precautions: What Is Density of Tribo-electric System Dust Monitor
The output value of the Dust Monitor of the Tribo-electric System varies according to
various environmental factors such as “kind of particle”, “diameter of
particle,”“gravity,” or “flow speed” due to its measurement principle, which can
be seen in the formula in section 1.
However, the linearity will not change except under certain environmental conditions.
For the density of the Dust Monitor of the Tribo-electric System, consideration must be
given to the influence by changes of physical characters as mentioned above.
Therefore, it does not always correspond to the density specified in section 6-2.
The density described in section 6-2 is assumed to be at the stages of design and development
of the Dust Monitor, and announced as the guideline for the user to determine the range.
When the user determines the range, check the pulse signal percentages output between
0% and 100%, and then set the appropriate values.
In this way, the tendency of the discharged dust density in the facility can be controlled.
When the density control is needed, the user must determine the density corresponding
to 0% to 100% signals.
After determining the range (0% to 100%) of the density control, check the actual density
when a pulse signal is input to the Dust Monitor.
After that, adjust the range or integral function to obtain the current signal optimal
to the actual density so that the user can read the signal as density from the current
signal of the Dust Monitor.
(This value is not an absolute value but a relatively converted value.)

７．INTEGRAL SETTING
The Dust Monitor can be set to output an averaged measuring signal by adjusting the Integration
Volume (Data averaging).
Follow the procedures below to carry out integral setting.
(The Integration Volume is set to “0 s” at our factory before shipment, unless otherwise
requested.)
1) Set the Range Switch to “0”.
2) Press the Mode Change Switch until the LED lamp “I.TIME SET” lights up.
(The integral setting can be adjusted while “I.TIME SET” is lit.)
3) Turn the Integration Volume clockwise (Arbitrary setting).
(For your reference: Each LED lamp on the display shows three seconds. (30 seconds max.))
4) To complete the integral setting, change the Range Switch to a value other than “0”.
If the Integration Volume is turned fully counterclockwise, the integral time will be set
to 0 seconds.
If a more detailed setting is needed, connect a tester to the output terminal of 4mA to 20mA
and adjust the Integration Volume by referring to the current value.
0 s (4mA) to 30 s (20mA)
Refer to 10.MAINTENANCE MODE .
The rapid rise of an output signal shows an error in the filter system.
Analyze the filter system under the Normal mode.
Turn off the Integral mode.
In Normal mode, rapid variation of the dust density can also be monitored.
Figure 5 shows an example of monitoring a 13-line bug filter using the Dust Monitor.
Regarding dust emissions, the signal peaks indicate a low amount of dust being processed in lines
1 to 6 as well as in line 12 and 13, and a high amount of dust being processed in line 7 to 11.
According to this, the judgment whether or not the filter needs to be replaced is possible.
Filter No.

８．LIMIT SETTING
In limit setting, the upper limit point (contact output point) can be set within the range of
4mA (0%) to 20mA (100%).
Follow the procedures below to carry out limit setting.
(The Limit Setting Volume is set to 12mA (50%) at our factory before shipment, unless otherwise
requested.)
1) Set the Range Switch to “0”.
2) Press the Mode Change Switch until the LED lamp “LIMIT SET” lights up.
(The limit setting can be adjusted while “LIMIT SET” is lit.)
3) Turn the Limit Setting Volume clockwise (Arbitrary setting).
(For your reference: Each LED lamp on the display shows 10%. (100% max.))
4) To complete the limit setting, change the Limit Setting Volume to a value other than “0”.
If the Limit Setting Volume is turned fully counterclockwise, an upper limit alarm will
be output at 4mA (0%) or more.
However, there is a possibility that a lot of chattering is generated when the change in the
signal is extreme.
In such a case, we recommend the integration mode or use the delay function by customer .
If a more detailed setting is needed, connect a tester to the output terminal of 4mA to 20mA,
and adjust the Limit Setting Volume by referring to the current value.
0% (4mA) to 100% (20mA)
Refer to 10.MAINTENANCE MODE .

９．MAINTENANCE
Use a rag to periodically clean the probe.
Maintenance scheduling depends on what is being measured and under what conditions.
As outlined in the guidelines, we recommend cleaning the probe at least once every three months.
Turn off the power before cleaning.
Be careful not to burn yourself when removing the probe.
As the temperature in the pipe increases, the temperature of the dust monitor also increases.
Caution: The earth line should not be removed even at the maintenance in case
it may cause a fault.
１０．MAINTENANCE MODE
Maintenance mode can be used to confirm “current signal adjustment”, “simulated alarm output”,
“limit setting value”, and “integral setting value” by setting the Range Switch to “0”.
To use maintenance mode, connect a device with 4 to 20 DC mA measurements such as a tester to
the current output terminal.
Importance: During maintenance mode, the LED lamp “Alarm”(red) will light up and output an
alarm contact.
This mode can also be used for a loop check of the alarm when performing a trial
operation.
If you change to maintenance mode during normal operation, an alarm signal will
be output. Be careful when using maintenance mode.
Importance: When switching from the maintenance mode to the measurement mode, please reset the
power supply.
10-1. Adjustment for current signal
1) Set the Range Switch to“0”while pressing the Mode Change Switch.
2) Keep pressing the Mode Change Switch (for more than five seconds) and both the LED “LIMIT
SET” and “I.TIME SET” will light up.
The current signal can be adjusted in this condition.
3) Release your finger from the Mode Change Switch, and 4mA will be forced to output.
If the output value differs considerably from 4mA, adjust it to 4mA with the 4mA Volume.
4) Press the Mode Change Switch again, and 20mA will be forced to output.
(At the same time, all LEDs will light up.)
If the output value differs considerably from 20mA, adjust it to 20mA with the 20mA Volume.
5) After that, each time you press the Mode Change Switch, 4mA or 20mA will alternately be
forced to output.
To return to the normal setting mode, change the Range Switch to a value other than“0”.
10-2. Confirmation for Limit and Integration
1) Set the Range Switch to“0”.
2) Press the Mode Change Switch once.
The LED lamp “LIMIT SET”(Limit setting LED) will light up. Limit setting can be adjusted
in this condition.
(For your reference: Each LED lamp on the display shows 10%.)
If a more detailed setting is needed, adjust the “LIMIT adj.” Volume by referring to the
current output signal using a tester.
3) After the limit adjustment is completed, press the Mode Change Switch again.
4) The LED lamp “LIMIT SET”(Limit setting LED) will go out and the LED lamp “I.TIME
SET”(Integral setting LED) will light up. The integral setting can be adjusted in this
condition.
(For your reference: Each LED lamp on the display shows 3 seconds.)
If a more detailed setting is needed, adjust the “I TIME adj.” Volume by referring to
the current output signal using a tester.
(For a current output value corresponding to the time (second) to be set, use the formula
below.)
5) After that, each time you press the Mode Change Switch, the limit setting or integral setting
can be alternately adjusted.
