Product Introduction
The gas concentration detector is a detector with low-power modular design, intelligent sensor detection technology, overall flameproof (D) structure, and fixed installation. The standard configuration is LCDTFT high-definition liquid crystal display, three-wire 4~20mA analog, RS485 digital and switching signal output, according to user needs to provide customized products, but also support output signal fine-tuning and other functions, convenient system networking and maintenance.
The rugged explosion-proof housing of the gas concentration detector is widely used in petroleum, chemical, metallurgy, fire protection, coal mine, cement, spraying, metal grinding, electric power, shipbuilding, environmental protection, telecommunications, biochemical and other industries.
Features:
The customizable range intelligent sensor is used to ensure the advantages of high sensitivity, high accuracy, linear stability and fast response of the detector.
The MCU chip is used, highlighting the low power consumption, safe and reliable performance, accurate data conversion, stable signal output, etc. 4-20mA, RS485, switching volume and other signal outputs, convenient to access PLC, DCS, DDC and other industrial control systems, or a single machine can link fans, solenoid valves and other control equipment through the switching volume;
Support customized wireless signal transmission: Zigbee, LORA, 433M, 4G, WiFi, NB, GPRS, etc.;
Dot matrix high-definition LCDTFT LCD display, Chinese and English operation interface can be switched by yourself;
The detector can be operated by remote control without opening the lid to alarm value, zeroing, calibration, reset, modifying address code and other functions;
Local integrated sound and light alarm indication, which can realize remote mobile phones, computers, monitoring rooms, third-party platforms, etc. alarm prompts through alarm control host or wireless signal, and can also be infrared remote control one-click silence;
Aluminum alloy casting explosion-proof shell, strong and durable;
It has passed a variety of international certifications such as CMA, CNAS, CE, ROHS, SIL, UL report safety, etc.
Explosion-proof certificate rating: Ex db IIC T6 Gb;
Degree of protection: IP66
