Overview
The online all-in-one detector is a detection instrument with low power consumption Modular design, intelligent Sensor detection technology, overall flameproof (d) structure, and fixed Installation method. The standard configuration is LCDTFT high definition LCD display, three-wire system 4~ 20mA analog, RS485 digital and switching signal output, and provides customized products according to user requests. It also supports Output signal fine-tuning and other functions, which is convenient for system networking and maintenance. The rugged explosion-proof shell of the instrument is widely used in petroleum, chemical industry, metallurgy, fire protection, coal mine, cement, lame plating, metal sanding, electric power, marine, environmental protection, telecommunications, biochemical medical and other industries.
