gas alarm
The SKA/NE-301 gas alarm adopts intelligent EC sensors and intrinsic safety technology, which can support multi gas and multi range detection. Our company can provide customized products according to user needs, with digital module design. It can be used without zero calibration or calibration during on-site replacement. This alarm can be installed in hazardous indoor and outdoor environments. When there is a measured gas in the air, the detector outputs an electrical signal proportional to the gas concentration. This electrical signal can also be transmitted wirelessly to DCS or other secondary instruments for centralized monitoring of information. The intrinsically safe circuit design is equipped with an all aluminum alloy explosion-proof shell, which is safe and reliable with advantages such as stable signal, high precision, and good repeatability. The explosion-proof wiring method is suitable for various hazardous areas. The instrument is compatible with various control systems such as alarm, PLC, DCS, etc., and can achieve remote monitoring, remote control, remote alarm, computer data storage, analysis and other functions.
