Dust Particle Sensor
Dust sensor has been designed to detect the level of
dust particles in the air. The air is sucked in through
the air inlet on the side and released through the
outlet on the top. Once the air comes in contact with
the sensor the level of dust particles is measured
and reported through the software.
Please note that the dust sensor must be fitted
sideways and the air inlet and outlet should not be
blocked.
Dust sensor is directly connected to the i-BOX
through one of the 14 ports on the back using a standard sensor cable. Once the sensor is
detected by the i-BOX, a new device wizard will appear on the screen. Follow the on-screen
prompts to add the sensor to the database.
Dust sensor settings could be accessed in the environment section. On the main screen click on
the environment button. Select the appropriate i-BOX from the menu on the left and click on the
dust particle sensor.
You may use the default settings by pressing the Auto Setup button at the bottom of the screen;
or you can use alternative settings due to different environmental conditions. Read frequency
indicates how often the sensor measures the level of particles in the air; Reporting frequency
shows how often the reading is reported & Store frequency indicates how often the reading is
stored in the log file. The status reading could be in the range of 1000 to 8500. If you wish to
lower this figure go to the calibration settings by clicking on the advanced button. The status
reading is directly affected by the value of C2. That means by decreasing the value of C2, you
could lower the range of status reading.
By enabling the Change function the software will notify you if there is a sudden change in the
level of dust particles in the air. Define the minimum and maximum limits and press save.
Depending on the environmental conditions the normal reading varies in the range of 1500 to
2500.
If the level of particles in the air exceeds the defined limits, the software will notify the user by
going into the alarm mode. Instantly an alarm transaction will appear on the main screen stating
the date & time and the type of the alarm. All the alarms and routine readings can be observed in
the Reports section.
