Direct reading dust concentration measuring instrument

One, overview
    1 product features
    CCZ-1000 direct reading type dust concentration measurement instrument suitable for portable dust concentration in coal mines or other dust working environment in determining total dust or respirable dust concentration and direct reading instrument, the instrument to beta ray absorption method principle, separation efficiency of the impact of respiratory dust separation device in accordance with international standards "BMRC". The dust separation efficiency curve, the instrument has good stability, high accuracy, precision is not affected by the influence of dust properties. To provide the measurement of dust concentration means fast, reliable for industrial and mining enterprises and other needed to measure the environmental dust places. The instrument is also equipped with a special PC communication software, the use of PC USB interface and the dust concentration measurement instrument communication, 2 for data analysis and processing.
    The 2 main purpose and scope of use
    This device can be used for total dust concentration and respiratory dust concentration determination of various dust in coal mines or other dust in working environment. Direct reading type dust concentration measurement instrument can be used for the direct determination of dust concentration of dust coal dust, gas or other dust in working environment.
    Type 3 and type name
    Model description:
    4 explosion-proof type and explosion-proof mark
    Explosion proof type: Mining intrinsic safety type
    Explosion-proof symbol: Exib 1
    5 the use of environmental conditions
    Working temperature: 0 ℃ ~40 ℃
    Relative humidity: ≤ 95%

Two, the work principle and structure feature
    CCZ-1000 direct reading type dust concentration measurement instrument consists of sampling head, detection device, intrinsically safe power supply, single chip microcomputer system and other flow sensors.
    Direct reading dust concentration measuring instrument work principle: membrane will first put blank membrane inserted into the detection device, the detection system of device quality of blank membrane were measured, the measurement results of I1 and memory, then the membrane clip out into the sampling head seat, tighten the sampling head after sampling, sampling by the micro motor drives the vane pump, negative pressure will be dust laden air pumped into the filter, and the sampling synchronous timer begins timing, digital display of the digital representation of the sampling time, when measuring instrument when sampling stop showing the total sampling time, and automatically stored, and then filter out into the clip to measure filter quality sampling detection device, the measurement results of I2 and memory, the data processing by the MCU and the dust concentration will be calculated and displayed on a display screen, and automatically stored.
Three, technical indicators
    Concentration measurement range: 0.5~1000mg/m ³
    The sampling flow rate: 15L/min
    The sampling flow rate error: ≤ 2.5%
    The sampling flow rate stability: ≤ 5%
    Accuracy: ≤ 20%
    Power supply: battery consists of a group of two ICP7S type lithium battery, series 1.5 Ω /20W current limiting resistor, a battery box is sealed by epoxy resin as a whole, form the intrinsically safe battery assembly. Ue=7.2V Uo=8.4V Io=4
