Description
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, durée de vie prolongée, et un fonctionnement convivial. 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, alarme, and control in environments containing gases, y compris les gazoducs, tunnels de services publics municipaux, instituts de recherche, hôpitaux, et les écoles. 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.
