Met OneofBAM-1020The particle monitor adoptsβThe principle of radiation attenuation is used to monitor particles. It has been approved by the US Environmental Protection Agency（EPA）The certification（EQPM-0798-122）And it is automatically monitored and recorded in the UK, South Korea, and ChinaPM10In the field of concentration applications, corresponding certificates have also been obtained.

BAM-1020Can be achieved through equipmentPM2.5Sampling ports can be used to automatically monitor smaller particulate matter and can also be used to monitor total suspended particulate matter（TSP）.

BAM-1020Fully automated measurement is achieved through advanced microprocessor control system. At the beginning of sampling, the monitor emitsβThe radiation is measured through the clean surface of a filter belt, and then the cross-section of the filter belt is pushed to the sampling port. The particulate matter is sucked into the sampling port and deposited on the filter paper. After the sampling is completed, the filter belt returns to its original position, and the cross-section is re measuredβRadiation can accurately determine particle concentration by comparing two measurement results.

BAM-1020Being able to evaluate the operational status in real-time to ensure the best credibility and highest data repair quality, users can choose various standards based on their data needs, including deviations from the average, deviations from high values, and many other conventional standard identifiers such as system power outages. These identifiers with date, time, and type will be recorded and printed out during daily data repair. The automatic zero and drift calibration performed in each cycle ensures reliable and accurate measurements. In the event of instrument failure, incorrect identification will be stored and the data will be considered invalid. The zero point test is conducted at the beginning and end of each cycle,BAM-1020Normal output can still be maintained when measuring blank filter paper. Drift measurement is achieved by automatically inserting a reference film along the measurement path.

【 Working Principle 】

BAM-1020Through advanced microprocessor system control, full automation is achieved, and at the beginning of sampling, the emittedBetaThe radiation is measured through the clean surface of a filter belt, and then the cross-section of the filter belt is pushed to the sampling port. The particulate matter is sucked into the sampling port and deposited on the filter paper. After the sampling is completed, the filter belt returns to its original position, and the cross-section is re measuredBetaRadiation can accurately determine particle concentration by comparing two different measurement results.

Adopting this approachBetaThe principle of radiation attenuation measures the density of mass particles, a small14CShooting line source（BetaConnect a sensitive X-ray to calculate the emissionBetaParticle detector. The filter belt is placed inBetaWhen the particles deposited on the filter belt increase between the radiation source and the detectorBetaThe particles will decrease (according to a certain relationship).

Structural Design

The technology of filter belt conveyor system has been used in Japan for more than 20 years,MetoneThe company is currently developingBAM-1020The transmission system has applied for a patent, which embodies advanced design quality and accuracy. In order to ensure the accuracy of data, an improved electronic measurement system adoptsA-BusThe microprocessor controller and data collector can be operated through a unique control panel.

Advanced communication options and controls include two serial ports, analog and alarm interfaces.

Communication serial port1# Used for data transmission and instrument operation status, this communication is usually associated withMODEMUsed together for remote communication.

Serial port2# is simply an output port used in conjunction with a printer or computer, through which date, time, data printing output, or one of two diagnostic modes can be set. Multiple communication options are available.

Online confirmation of data

BAM-1020Being able to evaluate the operational status in real-time to ensure the best credibility and highest data repair quality, users can choose various standards based on their data needs, including deviations from the average, deviations from high values, and many other conventional standard identifiers such as system power outages. These identifiers with date, time, and type will be recorded and printed out during daily data repair.

For users, the most helpful thing is not to use serial communication. Users can use analog information to obtain data or run problems, and then use it toModemConnect for diagnosis or inquire about error identification through a computer.

Self calibration

The automatic zero and drift calibration performed in each cycle ensures reliable and accurate measurements. In the event of instrument failure, incorrect identification will be stored and the data will be considered invalid. The zero point test is conducted at the beginning and end of each cycle,BAM-1020Normal output can still be maintained when measuring blank filter paper. Drift measurement is achieved by automatically inserting a reference film along the measurement path.
