Characteristics of dust concentration detector:

■ Customizable range intelligent sensor, using safety technology, supporting multi dust and multi range detection, with a range of 100ug/m3 to 1000mg/m3, and can provide customized products according to user needs;

■ The use of MCU chips highlights the detector's low power consumption, safe and reliable performance, precise data conversion, stable signal output, and more; Multiple signal outputs such as 4-20mA, RS485, and switch values are convenient for connecting to industrial control systems such as PLC, DCS, and DDC. It can also be used to control equipment such as fans and solenoid valves through switch value linkage;

■ Support customized wireless signal transmission: Zigbee, LORA, 433M, 4G, WiFi, NB, GPRS, etc;

■ Dot matrix high-definition LCD TFT display screen, with a Chinese English interface that can be switched by oneself;

■ The detector can be operated through remote control without opening the cover, including functions such as alarm value, zero adjustment, calibration, reset, and address code modification;

■ Local integrated sound and light alarm indication, which can achieve remote alarm prompts for mobile phones, computers, monitoring rooms, third-party platforms, etc. through alarm control host or wireless signals. It can also be remotely controlled by infrared with one click silencing;

■ Aluminum alloy cast explosion-proof shell, sturdy and durable;

■ Through various international certifications such as CMA, CNAS, CE, ROHS, SIL, UL, ECM safety, etc.

■ Explosion proof certificate level: Ex db eb mb IIC T4 Gb; Ex mb tb IIIC T130℃ Db；

■ Explosion proof certificate number: SYEx23.0499;

■ Protection level: IP65;

Product parameters of dust concentration detector：

Dust concentration detector installation location:

1: Dust concentration measuring instrument, fixed, the design institute generally requires split-line installation;

2: where the belt is transported, installed between 0.5-2 meters above the reproduction point;

3: production-type workshop, installed in the workshop column or wall about 2.5 meters;

4: Where there is a grinding machine, install between 0.5-2 meters above the grinding machine;

5: coal dust, flour, and so on, the place of stacking, called the production into the point, installed in the production into the point of the top, for example, coal dust 15 meters high,to be installed in the top of this 0.5-2 meters high, that is, about 18 meters.
