Product description
The series of 485 main line gas detection alarm system adopts non-standard agreement or MOdBUS protocol for data collection and transmission. The intelligent transmitter node acquisition collects and detects the gas concentration on the spot. The host round tests various nodes with intelligent background software, and monitoring the gas concentration changes in real-time.
Our product uses the bus-system, having strong anti-jamming capability, convenient layout and simple wiring. At the same time, it also provides an controlling external device (exhaust fan, solenoid valve, etc.) of the switch output. The detector detects gas concentration with natural diffusion mode, which uses the imported sensors and has a good sensitivity and repeatability.
This instrument uses the embedded micro-controller control technology, simple menu operation, complete functions and high reliability. Bus-system gas detection transmitter adopts aluminum shell material with high strength, heat resistance and corrosion resistance. Our product is suitable for the detection of poisonous and harmful, inflammable and explosive gas in the air and has been widely used in metallurgy, power plant, chemical industry, mine, tunnel, tunnels, underground pipeline and other places, effectively preventing the happening of the accident.

The Tire derived Steel or Tire Wire Scrap is a light melting scrap obtained during the shredding and granulation process of used tires. Generally 10% - 20% of the weight of an old passenger car tyre usually consists of steel. An average shredding plant produces about 100-200 MT of steel tyre wire and its quality can vary according to technology, storing and management systems adopted by the producing plants. We can provide tire wire scrap that still contains up to 20% rubber/fiber. This percentage is detected by manual separation test. The material can be loaded loose in 40 HC container.
