Characteristics of dust concentration detector£º

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

¡ö 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;

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

¡ö Dot matrix high-definition LCD TFT display screen, with Chinese and English operation interfaces that can be switched by oneself;

¡ö 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;

¡ö 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 ¡ö host or wireless signals. It can also be remotely controlled by infrared with one click silencing;

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

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

¡ö Explosion proof certificate level: Ex db eb mb IIC T4 Gb; Ex mb tb IIIC T130¡æ Db£»

¡ö Explosion proof certificate number: SYEx23.0499;

¡ö Protection level: IP65;
