1.1 Optical Particle Counter
Aeroqual uses an OEM optical particle counter from Met One
Instruments. The particle counter uses scattered light to measure and count particles. Light from a laser diode is collimated to illuminate the aerosol sample flow. When a particle is present it scatters the incident laser light which is detected using a 60 o
solid angle elliptical mirror at right angles to the laser beam. The amount of scattered light is converted to a voltage pulse and the amplitude of the pulse is calibrated to a particle diameter. The particles are thus assigned on the basis of size to one of eight channels.
Safety: This sensor is considered a Class I laser product. Class I laser products are not considered to be hazardous. There are no user serviceable parts inside the cover of the sensor. The device contains a laser operating at 670 nm which is visible to the eye and can cause damage to the eye if directly exposed. Only trained service personnel should attempt servicing or repair of the sensor.
1.1.1 Electrical connections
The connections to the optical particle counter are at the bottom of the unit. There is also a LED which turns red if there is a fault condition (see Troubleshooting section). The optical unit also requires an earth wire to be connected between the housing and the 0VDC line on the power bus. Please check that this is fitted if the unit has been replaced.

The Dust Profiler is supplied with a RS232 to USB adapter fitted between the Control Module and an external USB socket fitted at the base of the enclosure. This enables the user to perform a wide range of functions over the USB connection, without needing to open the enclosure door, such as data logging and various system checks using the supplied Aeroqual Dust Profiler PC software.
Note 1: The driver for the RS232 to USB adapter is in the USB stick which comes with the instrument.
Note 2: The power to sensor and alarm relays are also attached to the control module base plate.
WWW.DUSTSENTRY.NL | +31 70 413 70 50
1.4. Power Module
The Dust Profiler internal power requires regulated 12 VDC to maintain a constant pump speed. An external mains to 12VDC power supply (Meanwell HLG80-12A 60W 12V) is fitted on the outside of the enclosure and this will allow connection to mains supply.
Note: If you wish to run the Dust Profiler on solar power you will need to use a DC-DC convertor in order to supply a regulated 12 VDC for the Dust Profiler
– refer to the application notes on the website
1.5. Analogue Output Module (Optional)
The Dust Sentry has the option to integrate an ADAM 4021 Analogue Output Module into the system to allow for the digital inputs of a chosen sensor to be converted to an analogue output. The analogue output module receives the digital input via an RS485 interface and converts it to a 4-20mA and 2-
10V output. These outputs follow each other.
Outputs:
4mA (2V) = 0% of full scale value.
12mA (6V) = 50% of full scale value.
20mA (10V) = 100% of full scale value.
The module is easily configured via the Operations menu in the PC software and can convert to an analogue output any chosen sensor already integrated in the Dust Sentry. The module uses the logging period to calculate the reading, which is also set in the Operations menu. This differs from the alarm relay, SMS and email which all use the averaged alarm period to calculate the reading. For more information regarding the PC Software and setting up the analogue output module please refer to Section 3.1.
1.6. Auxiliary Module (Optional)
The auxiliary module acts as an interface between third party sensors and the Dust Profiler communication bus. It is configured with different operating modes which can be selected by using the dipswitches located on the side of the module. Aeroqual has integrated a number of third party sensors and is able to supply the auxiliary module preconfigured for your sensors.

1.9. Alarm Relay
The Dust Profiler has a built in alarm relay function that is set up via the Operation Dialog in the PC software (See Section 3.1.)
Relay Output:
This is fitted as standard and is activated by “Enable Alarm Relay Output” tick box. If the set point set in “Alarm trigger point” is exceeded the relay is activated. This can be used to activate a siren or strobe or other peripheral devices. The relay remains activated until the measured value drops below the reset point (expressed as a % of the trigger point). This is controlled via the
“Alarm reset point of trigger”. The “Alarm trigger point average period” determines the amount of time that the concentration needs to be exceeding the trigger point before the relay is activated.
If “Active output on diagnostics” is selected the alarm will trigger upon sensor failure or sensor no report. If not selected the alarms remain in the state they were in when the last valid reading was logged.
The Alarm relay is energised by the Control Module in response to the alarm trigger point. The trigger point is programmed into the Control Module via the Operation menu in the PC Software. The Alarm
Relay is a double pole; double throw type (see diagrams below). This allows the connection of two different alarm signals
– e.g. siren and strobe - that may have different power requirements.
The relay contacts rating: 2 x 5A @ 24VDC 220VAC.

3.3.1. Further information about IP address solutions using GPRS Systems
GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more prevalent, but the dynamic IP address issues associated with GPRS networking continue to frustrate system integrators.
The trouble with I/O devices with GPRS capability is that they receive a different IP address every time they connect to the GPRS network.
Three distinct solutions have been developed to overcome this challenge:
Solution 1: Public Static IP Address
The first option is to obtain a public static IP address; some carriers (telecom service providers) can assign a static IP address to a specific SIM card. This way, all the I/O devices will have their own static IP address. The main benefit of this solution is that it behaves like a wired solution. However, not all carriers offer this kind of service.
Solution 2: VPN Service Provided by Carrier/MVNO
A VPN (Virtual Private Network) is a secure LAN solution that groups specific devices together. The
VPN grouping concept solves the dynamic IP address issues and prevents unauthorized persons from accessing the data. For this VPN solution, customers are required to buy one of a number of different GPRS on-line services to be able to access a Virtual Private Network (VPN). When the
GPRS device dials up, the carrier will assign a private IP address which is on the same network segment as the host and can maintain bi-directional communication using a polling architecture. Many enterprise clients turn to mobile virtual network operators (MVNO). These MVNO’s acquire numerous
GPRS services and then rents them out to customers who are looking for a small number of IP addresses.
Unfortunately, some countries do not have MVNOs, and some carriers do not provide VPN services.
For this reason, this solution may be unfeasible for some users.
Aeroqual has used www.wyless.com successfully to communicate with AQM instruments.
Solution 3: DDNS
Using dynamic IP addresses is often necessary since many ISPs do not provide static IP addresses.
The Dynamic Domain Name System (DDNS) is used to convert a device’s name into a dynamic IP address so that remote devices can communicate with the control centre using a fixed domain name.
DDNS takes care of the Dynamic IP address of a device, and DNS the static IP address of a device.
With most remote GPRS devices, you need to apply for a hostname for each of the devices handled by the DDNS server. When GPRS devices get an IP address from the carrier, they will automatically connect to the GPRS network. Each time a GPRS device’s built-in DDNS client gets a new IP address, it will send the IP address to the DDNS sever.
Aeroqual has integrated the “DynDNS Pro” service from http://dyn.com
with your GateTel modem. For a small annual fee you can configure up to 30 host names to use with up to 30 modems.

Note 1: Suggested intervals for maintenance procedures may vary with sampling intensity and environmental conditions
Note 2: All checks should be carried out during the initial commissioning of the Dust Profiler
4.2. Maintenance Procedures
4.2.1. Sample Flow Check and Adjustment
A set flow rate is essential to ensure consistency in the measurement. To measure the flow, remove the TSP head and connect the volumetric flow meter to the top of the inlet using the adaptor supplied with the instrument. Ensure the flow meter is on a steady surface before reading the flow rate.
Note 1: The adaptor tubing should be connected to the TOP of the volumetric flow meter
(negative flow)
Note 2: The flow should be 1.0 LPM
The inlet flow can be adjusted via the flow adjuster on the exhaust line.
If the flow is greater than 1.0 LPM then close the exhaust flow screw (turn clockwise) until
1.0 LPM is achieved.
If the flow is less than 1.0 LPM then open the exhaust flow screw (turn anticlockwise) until the flow is 1.0 LPM.
WWW.DUSTSENTRY.NL | +31 70 413 70 50
Afterwards replace the inlet components with care making sure there is no leak.
Exhaust adjustment
4.2.2. Sheath Flow Check
The sheath flow is a constant stream of air which ensures the optics remains clean. It is important this is working correctly to maintain the accuracy of the measurement. In order to check the flow, a volumetric flow meter needs to be connected between the purge flow adjuster and particle engine as seen in the diagram.
Note 1: The flow should be greater than 0.5 LPM
9722-1 engine
4.2.3. Leak Check
If the correct sample or sheath flow cannot be achieved, there may be a leak in the pump module or engine. First check the entire flow system:
Remove exhaust connection from the base of the enclosure
Remove the TSP head and block the PM inlet.
Connected the pressure end of a flow meter to the exhaust tubing.
If there is no leak the flow should drop to zero.
If the flow does not drop to zero it suggests there is a leak somewhere in the system. To check the pump module:
Remove the sample connection and cap off the module sample port.
Connect the exhaust port of the module to the pressure end of a flow meter.
The flow should drop to zero.
If there is a leak in the pump module the module will need to be sent back to the Aeroqual factory.
Please contact technical support.
If there is no leak in the pump module it is likely the leak is located in the engine. In this case, the engine will need to be sent back to the Aeroqual factory. Please contact technical support.
WWW.DUSTSENTRY.NL | +31 70 413 70 50
4.2.4. Manual Zero Air Check
A zero air check can be carried out manually. To do this the TSP inlet needs to be removed and the particle filter (supplied with the instrument) needs to be attached to the monitor. Ensure there is a good seal around the inlet.
The filter will remove 99.99% of particulates from ambient air. Wait 5 minutes and then check the readings on the control module. The reported value should be close to 0.0ug/m3.Record the particle monitor reading in µg/m
-3
and the Volt (V) reading from the diagnostics in the maintenance report.
4.2.5. Filter Changes
There are two green filters which are located to the left of the sample filter holder.
They are designed to provide protection to the pump and optical window. The filters will become dirty and must be replaced periodically.
To do this, unclip the filters from the connectors and replace. Ensure the filters are connected the right way in accordance to the flow arrow. These filters can be purchased from Aeroqual. Please contact technical support for a quotation.
Note: BQ filter – Sheath air filter (behind)
DQ filter – Sample air filter (in front)
4.2.6. Inlet Cleaning
The TSP inlet can be dismantled by unscrewing the 3 screws and separating the head into two parts.
Use a lint-free cloth wetted with isopropyl alcohol to clean both the inside and outside of the inlet.
Screws
4.2.7. Pump Module Removal
The pump module can be removed from the Dust Profiler by unscrewing the 4 screws on the base plate and sliding the module out. Ensure the Dust Profiler is switched off when removing the module.
The sample, purge and exhaust lines need to be disconnected and all the connected cables removed.
The two main failures which would require removal of the pump module are:
1. A leak is discovered
2. The pump requires replacement
In both these cases the pump module will need to be sent back to the Aeroqual factory for repair.
Please contact technical support for assistance.
WWW.DUSTSENTRY.NL | +31 70 413 70 50
5. Calibration
All particle monitors based on light scattering require a site calibration for optimum accuracy. This is because the average density and light scattering behaviour of dust particles will vary from site to site.
This adjustment is sometimes known as a “K-factor”. Aeroqual recommends a site calibration be performed at the time of initial installation and then every 6-12 months. Calibration is performed by colocating the Dust Profiler with a Reference Particulate Matter measurement system and adjusting the
Gain of the particle monitor so the average reading matches that of the Reference Instrument. A list of
Reference instruments can be found at: http://www.epa.gov/ttnamti1/files/ambient/criteria/reference-equivalent-methods-list.pdf
Install the Dust Profiler beside the Reference instrument. Make sure both instruments are setup correctly. Two procedures are given below depending on whether the reference instrument is a gravimetric or continuous instrument.
Procedure overview for Gravimetric Reference Instrument
1. Weigh a reference filter and install into the Reference instrument.
2. Leave the Dust Profiler and Reference instrument running for at least 24 hours until a weighable quantity of particulate matter sample has been collected.
3. Check the sample flows of both instruments to ensure they are within specification.
4. Remove the Reference filter and re-weigh
5. Download the Dust Profiler PM data for the calibration period.
Calculations
1. Reference Filter Weight of PM (ug):
PM(Ref) = (filter weight at finish)
– (filter weight at start)
2. Volume of air sampled by reference sampler (m3)
Volume(Ref) = minutes of test * Flow Ref (LPM) / 1000
3. Calculate average reference PM density (ug/m3)
AvPM(Ref) = PM(Ref)/ Volume(Ref)
4. Calculate average AQM60 PM (ug/m3):
AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings
Procedure overview for a Continuous Reference Instrument
1. Leave the Dust Profiler and Reference instrument running for at least 24 hours
2. Check the sample flows of both instruments to ensure they are within specification.
3. Download the Dust Profiler and Reference instrument data for the calibration period
Calculations
1. Calculate average Dust Profiler PM (ug/m3):
AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings
2. Calculate average Reference PM (ug/m3):
AvPM(Ref) = sum(PM readings over test period)/number of readings
Calculation of Dust Profiler Gain
1. Calculate K factor
K factor = AvPM(Ref) / AvPM(Dust Profiler)
2. You should then apply this to the Gain Factor on all the PM channels.
new GAIN = old GAIN x K Factor

10. Mounting and Site Positioning Guidelines
It is important that the positioning of the Dust Profiler is suitable so as to yield data which is representative of that specific location.
10.1. Mounting
The Dust Profiler comes with 2x mounting brackets and 3x U-bolts for 2 inch poles. The same brackets are used for both pole and wall mounting.
To wall mount the Dust Profiler the brackets are screwed into the wall instead of using the U-bolts.
For pole mounting:
1. Secure top mounting bracket at a suitable height using 2x U-bolts provided
2. Fix lower mounting bracket to the Dust Profiler chassis with screws
3. Hang the Dust Profiler on the top mounting bracket
4. Place U-bolt through lower mounting bracket
Note: Only one U-bolt is used to secure the bottom bracket
5. Add nuts and washers and tighten the bottom U-bolt into position
1.
2.
3
.
4
.

.
10.2. Inlet height
If PM monitoring is related to human exposure, the sampling inlet height should be positioned in the “breathing zone”. This is located between 2 and 15 meters above ground level.
If PM monitoring is related to specific emission sources, the position of the sampling inlet can be more flexible. It is more important that there is no obstruction between the approaching air from the emission source and the sampling inlet.
If more than one Dust Profiler, or any other particulate instrument, is being used at the site, the height of the inlets should be uniform.
If the Dust Profiler inlet is the highest point at the site, a lightning rod must be installed to prevent damage to the unit during electrical storms.
WWW.DUSTSENTRY.NL | +31 70 413 70 50
10.3. Measurement Interference
The meteorological conditions of the site should be taken into consideration when positioning the Dust Profiler. For example, there should be no obstruction to the air flow in the predominant wind direction. A minimum clear sky angle of 120 degrees is recommended.
The inlet should be at least 1 meter away from any objects that could potentially influence the airflow characteristics e.g. trees, vertical surfaces or walls.
Avoid overhead high-voltage cables which may cause electrical interference with the sampling equipment.
Demolition/construction activities and change to normal transport patterns due to road works etc. can significantly affect the data. Ensure a record of such events is kept to account for unexpected peaks in concentration.
10.4. Safety
The intended data capture rate should be considered when positioning the Dust Profiler. If data capture above 90% is essential, the unit should be located in an area which has 24 hour access available.
The positioning should allow for routine maintenance checks to be performed safely by personnel.
If using a tripod, ensure the tripod legs are bolted to the ground to prevent the unit from falling. Ensure the Dust Profiler is in a secure location to avoid vandalism or theft
