ZGF-2A Individual Explosion proof Dust Sampler

　　Place of Origin:Domestic production

Instrument Overview:

The ZGF-2A individual explosion-proof dust sampler is an instrument used to measure the average concentration of air dust in a work shift. This instrument is designed according to MT162-95 "General Technical Conditions for Workplace Dust Samplers", Q/ZG-02-2007 Dust Sampler Enterprise Standard, and GB3836.4-2000 standard Exibl level (intrinsic safety type) explosion-proof design. It has the characteristics of small sampling airflow pulsation, large load capacity, stable flow rate, easy operation, safety and reliability, and easy portability. Its separation efficiency for respiratory dust meets the requirements of the "BMRC" international standard curve, and is particularly suitable for use in coal mines and other workplaces containing explosive gases.

Performance parameters:

Respiratory dust sampling: 2L/min

Sampling flow error: ≤ 5%

Sampling flow stability: ≤ 5%

Load capacity: ≥ 1000Pa

Continuous working time: ≥ 10h

Work noise: ≤ 65dB (A)

Sampling time error: not exceeding 1.0S within 5 minutes

Sampling efficiency: Total dust and respiratory dust comply with the "BMRC" sampling efficiency curve

Dimensions: 120 × 80 × 42 (mm)

Weight: 450g

Working temperature: -5~45 ℃

Relative humidity: ≤ 95%

Working power supply: Using Ni-H1.3A/h, 5 sections, connected in series with 6 current limiting resistors of 0.15 Ω/3W, sealed with epoxy resin and placed in the battery box. Its maximum output voltage U0=7V and maximum output current I0=2.1A constitute an intrinsic safety battery module.

Explosion proof type of instrument: mining intrinsic safety type, explosion-proof mark: Exibl
