YA-D400 Fixed Gas Detector with 24V Power, IP67 Rating, 205×209×84mm Dimensions for Industrial Combustible & Toxic Gas Monitoring
The YA-D400 series point type gas detectors are engineered for industrial safety applications in chemical plants, petroleum facilities, metallurgy operations, liquefied gas stations, painting operations, and gas transmission systems. These detectors monitor toxic and combustible gases in both indoor and outdoor environments where gas leaks pose significant risks.
This practical, easy-to-operate gas detector can be integrated with our YA-K series gas alarm controllers to create a comprehensive industrial gas alarm system. The unit supports wall-mounted installation (with optional tube, scaffolding, or ceiling mounting) and transmits data to controllers for processing, display, and output control functions.
- Real-time gas concentration display with clear backlit screen
- Comprehensive alarm system: fault, low, and high level alerts
- Infrared remote control operation eliminates need for cover removal
- Three distinct sound and light outputs for different alarm conditions
- Zero, calibration, and test functions for maintenance
- DC4-20mA standard signal output
- Multiple communication options: RS485, two buses, LoRa
- High-performance ARM microprocessor for reliable operation
- Three relay outputs (250V 5A) for automatic fan and solenoid valve control
- Storage capacity for 40 high and low alarm records
- Toxic gas units support mg/m³ and μmol/mol conversion
