Individual Dust Sampler main technical parameters:
Individual Dust Sampler is an instrument for measuring the average concentration of dust in the air of a work shift, which is suitable for underground sampling in coal mines.
1.Sampling flow rate: Respirable dust sampling: 2L/min (fixed flow rate)
2.Sampling flow error: ≤3%FS
3.Sampling flow stability: The sampling flow stability of the sampler within 8 hours is ≤3.0%FS
4.Load capacity: ≥1000Pa
5.Continuous working time: ≥8h
6.Working noise: ≤65dB (A)
7.Flow meter accuracy: not less than level 2.5
8.Sampling time error: ≤0.1% within 5 minutes
9.Average flow rate at sampling port: 0.5~4.0m/s
10.Air tightness: The sampling head and flow meter of the sampler are kept under a pressure difference of (1000-1100) Pa for 1 minute, and the pressure change shall not exceed 100 Pa.
11.Sampling accuracy error: ≤10%
12.Explosion-proof type: Mining intrinsically safe type ExibI (150°C), suitable for flammable and explosive workplaces and underground sampling in coal mines.
13.Sampling efficiency: in line with the "BMRC" sampling efficiency curve;
14.Dimensions: 120×80×42 (mm)
15.Weight: 450g
Moisture monitoring refers to the monitoring and assessment of soil moisture conditions to understand soil moisture content and soil moisture changes, which provides an important reference basis for agricultural production. Through moisture monitoring, the problem of soil water shortage or excess wa...
Soil moisture conditions, often referred to as soil moisture, are critical to agricultural production. Soil moisture is directly related to the growing conditions of crops and is one of the key environmental factors that determine the health of crops.Knowing the exact level of soil moisture and its...
In port and traffic-intensive areas, severe weather conditions such as fog and strong winds often have a serious impact on production and transport activities. Owing to the challenges of establishing meteorological observation facilities in these areas, there is a chronic lack of systematic observat...
The role of road weather monitoring system in highway construction is very important, and it is a new type of automatic weather station established on the basis of road weather service. It can not only realize real-time observation of road weather conditions and driving environment, but also provide...
