Toxic and flammable gas alarm

YA-D300/YA-D400 series dot typeToxic and flammable gas alarmWidely used in hazardous indoor and outdoor environments where toxic and flammable gases are generated, stored, and used, such as in chemical, petroleum, metallurgical, liquefied gas stations, painting operations, and gas transmission and distribution. The YA-D300/YA-D400 series point type gas detectors are practical and easy to operate gas detectors developed by our company. It can be combined with our company's YA-K series gas alarm controller to form an industrial gas alarm system.

This product is installed in a wall mounted (or pipe mounted, bracket mounted, suspended ceiling mounted) manner, and is used in conjunction with a controller to process various data uploaded by the gas detector through the microcontroller of the controller, ultimately achieving functions such as data display and output control.

Toxic and flammable gas alarmProduct Features:

1. Stable detection: Imported processing chips and sensors provide more sensitive detection and accurate data

2. Strong protection capability: IP67 high-level protection, mesh cover, wind cover sensor protection design, waterproof, dustproof and explosion-proof

Infrared remote control operation: No need to climb or open the cover, remote adjustment of values, reducing hardware loss and personnel injury

4. Rich and diverse output signals: supports 4-20mA, RS485, LoRa wireless, POWERBUS dual bus

5. LoRa wireless communication: low power consumption, no wiring, anti-interference, transmission distance of 3-5 kilometers, easy wall penetration, saving installation costs, solving wiring problems, suitable for use in complex factory environments

6. Strong recognizability: faults, low limits, and high limits correspond to different buzzer frequencies and limit alarm red backlight prompts, which are still clearly visible in dim environments

7. Multiple relay outputs: Three sets of relays correspond to fault, low limit, and high limit alarm outputs respectively

8. Data storage: can store 40 alarm records, easy to retrieve and query historical records

9. Excessive linkage: can be paired with external equipment such as solenoid valves, fans, and sprinklers, and automatically linked when exceeding the standard

10. Backend monitoring: Paired with cloud computing, it facilitates real-time viewing of backend data and supports multi-channel notifications and alerts such as SMS, phone calls, and WeChat mini programs

11. Easy installation: can be installed in various ways such as wall mounted, pipe mounted, bracket mounted, ceiling mounted, etc

12. Flexible Conversion: Toxic gas detectors can achieve conversion between mg/m3 and μ mol/mol
