Otywell | Producator de detectoare de gaz
Descriere
This product integrates high-performance gas-sensitive components and microcontroller technology with precision SMD manufacturing, delivering outstanding repeatability, reliable temperature/humidity performance, strong anti-interference capability, extended service life, and user-friendly operation. Designed for gas concentration and leakage detection, it converts ambient gas concentration signals into electrical signals. The output supports three-wire (4-20) mA current signals, RS485 four-wire bus signals, or two-wire configurations, featuring long-distance transmission and simplified wiring requirements.
This product is designed for gas safety detection, alarma, and control in environments containing gases, including gas pipelines, municipal utility tunnels, research institutions, hospitals, and schools. It is suitable for hazardous areas with explosive flammable gases classified as Grade II A to II C and temperature ranges of T1 to T6.
