  • Page 5: Description

    1. Description Aeroqual’s Dust Sentry Pro is a user friendly instrument designed to provide continuous particulate measurement of PM , PM , PM , and TSP. It uses an optical particle counter to count and classify particulate matter according to size. The instrument then converts the size distribution into a mass measurement.

  • Page 6: Optical Particle Counter

    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 solid angle elliptical mirror at right angles...

  • Page 8: Control Module

    1.3. Control Module The control module is the interface between the RS485 sensor bus and data communication links. It contains a display, a SD data card which logs data, a RS232 serial connector for external communication, a bus connector for internal communication with the sensor modules and a cable connector for the Sensiron Humidity and Temperature sensor (if fitted).

  • Page 9: Power Module

    1.4. Power Module The Dust Sentry Pro 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 Sentry Pro on solar power you will need to use a DC-DC convertor in order to supply a regulated 12 VDC for the Dust Sentry Pro –...

    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.

It is important this is working correctly to maintain the accuracy of the measurement.

  • Page 28: Manual Zero Air Check

    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.

  • Page 29: Calibration

    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.

    7. Specifications The Dust Profiler uses a Met One Instruments Inc. 9722-1 OEM Particle Counter which operates on the principle of light scatter from suspended particulates to provide a continuous real time measurement of airborne particulate. An algorithm is then used to calculate the equivalent mass concentration.
