Fixed HCN Gas Detector with Hot-Swappable, Pre-Calibrated Modules – GAOTek

Description Overview This industrial fixed gas detector is engineered to provide continuous 24/7 monitoring for Hydrogen Cyanide (HCN) while revolutionizing maintenance efficiency. Its unique, fully modular design is a key advantage, featuring separate, hot-swappable modules for the sensor, display, and control unit. This allows for incredibly fast and easy on-site servicing—simply swap a module without the need for complex re-calibration, saving significant time and cost. Built with a high-quality sensor in a rugged, explosion-proof housing, this detector ensures reliable performance and seamless integration into your control panel via 4-20mA or RS485 outputs.   Features Fully Modular Design (Sensor, Display, Control) Hot-Swappable, Pre-Calibrated Sensor Module No Re-Calibration Needed After Module Swap Simplified Maintenance, Reduced Downtime & Cost Industrial Outputs (4-20mA & RS485) Flameproof Explosion-Proof Housing (Ex dIICT6)   Technical Specifications Specification Description Working Power DC24V (Other power supply please contact us for solutions) Detection Range As per gas type (combustible gas, toxic gas and oxygen) Alarm Value 1st alarm as per gas type, 2nd alarm as per gas type Respond Time T90<30s Output Signal (4-20)mA or Digital signal Relay Yes, two passive output relays (AC220V 3A) Display LED display Working Temperature -40°C~ 70°C EX Grade Ex db IIC T6 Gb Certificates ATEX, SIL and CNEX Net Weight 1200g
