PURPOSE:
The meter for the mass concentration of dust is designed to measure the content of dust in the air of various origins and chemical composition while monitoring the excess of maximum permissible concentrations in the air of the working area, technological control of air conditioning systems, ventilation and cleanliness of objects for various purposes, as well as signaling when preset thresholds are exceeded after calibration by place of operation by the comparative method.
DESCRIPTION:
The frequency meter for dust concentration is based on an optical method for measuring the concentration of dust without preliminary deposition. The development uses the dependence of the reactive properties and negative resistance of semiconductor devices on the effect of external physical quantities and the creation on this basis of a new class of microelectronic frequency converters for the concentration of gases, dust, pressure, humidity and temperature.
TECHNICAL CHARACTERISTICS:
-
- time of one measurement – 15 s;
- measuring dust concentration through the first channel (particle size 0.2-2.5 microns) 0-50 mg / m3 is 0-150000 particles; on the second channel (particle size 2.5-10 microns) 0-250 mg / m3 – 0-250,000 particles;
- measurement error – 2.5%;
- device dimensions – 130x100x36 mm;
- weight – 220 g.
ADVANTAGES:
In the created device, the concentration of dust and other external influences is converted into a frequency signal, which makes it possible to create radio-measuring microelectronic converters using integrated technology and increase the speed, accuracy and sensitivity, expand the range of measured values, improve the reliability, stability and long-term stability of parameters.
RECOMMENDED FIELD OF APPLICATION:
The device can be used in security protection systems at airports, railway stations, metro stations, aircraft construction, space technology, chemical industry, mining, road transport, medicine, agriculture, for monitoring the environment in Ukraine and other countries.
RESULTS OF THE RESEARCH:
Ready for implementation.
STAGE OF THE DEVELOPMENT READINESS:
