I. Overview
HDL-FC-50G-EX Explosion-Proof Dust Continuous Monitor (hereinafter referred to as the Explosion-Proof Dust Monitor) is primarily used for the concentration detection and over-limit alarm of flammable and explosive dust particles in industrial and mining enterprises. This instrument draws in air containing dust particles from large public indoor spaces, industrial and mining enterprises, factory workshops, or production workshops, and analyzes it through a high-precision electrostatic dust detection sensor. The data is then displayed on the instrument's screen to show the dust concentration in the space.
HDL-FC-50G-EX Explosion-Proof Static Continuous Detector, utilizing advanced static principles for high-sensitivity, non-contact measurement of airborne dust. Managed and controlled by a single-chip microprocessor, featuring a high-resolution, large-screen, high-brightness LCD display.
II. Main Technical Specifications
1. Dust Measurement Categories: Coal Powder, Fly Ash, Metal Dust, Aluminum Powder, Magnesium Powder, Flour, Starch, Various Dusts
2. Dust Measurement Range: 0.1~50.0 g/m³, 0.1~100.0 g/m³; Customizable to various ranges.
3. Detection Sensitivity: 0.01g/m³; Repeatability Error: ≤±5%
4. Features over-dust concentration alarm setting, allowing you to set your own high-concentration alarm threshold. Equipped with an internal buzzer, it can also connect to external sound and light alarms. Switch quantity output can be connected to external exhaust fans. When the dust concentration exceeds the high threshold, the exhaust fan will automatically start to reduce the dust concentration in the space.
5. Equipped with an RS485 communication interface, 4-20mA current output, capable of connecting to a computer for data transfer, remote monitoring, and printing test results.
6. The instrument features a programmable clock chip, providing precise date and time information for measurement.
7. Working Environment: Temperature (-30 - 75℃); Humidity RH (20 - 80)%
8. Operating Power: 220V AC; or 24V DC
9. Instrument lifespan exceeds five years
10. Dimensions: 360mm x 320mm x 250mm
11. Protection Class: IP65 (Explosion-proof Mark: ExdIIBT6)
12. Weight: Approximately 3 kg
III. Features
This instrument's outer case is cast according to the national safety explosion-proof standard, with a thickness of 10mm and an explosion-proof grade of ExdIIBT6 Gb/EXtD A21IP65. It is mainly used in flammable and explosive environments, is easy to install, features fast testing speed, high sensitivity, good stability, simple operation, and is suitable for large factories and workshop measurements. Ensures safe production, real-time monitoring, and alarm functions.
Equipped with a dust concentration alarm function, capable of setting a high-concentration alarm threshold independently. Features an integrated buzzer and the option to connect an external sound and light alarm. The switch quantity output can be linked to an external exhaust fan. The fan automatically activates when the dust concentration exceeds the set high limit, reducing the dust concentration in the space.
IV. Applicable Occasions
HDL-FC-50G-EX Explosion-proof Dust Detector, suitable for rapid measurement of particulate matter concentration in public places, coal yards, coal storage sheds in power plants, coal piers, powder spray workshops, and high dust concentration in painting workshops. It is also used for dust explosion monitoring in metal processing and polishing workshops. The device can achieve sequential control of fans and fog cannons. It is used for dust concentration detection in industrial and mining production sites, as well as for monitoring inhalable dust concentration in environmental protection. It can also be used to evaluate the purification efficiency of air purifiers. Real-time dust concentration detection with alarm function in production workshops and factory interiors.
