Overview
GQ-DX101 Fixed Gas detector is a new type of detector developed by BOSEAN brand combined with many years of Gas detection experience. It is used to detect the concentration of flammable or toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value, it will issue sound and light alarms, and timely remind to take safety measures to prevent explosion and poisoning accidents and ensure the safety of life and property. The product has the advantages of stable signal, high accuracy, fast response, long life and short polarization time. It adopts industrial grade Sensor and explosion-proof structure design, supports 4-20mA standard signal or DOS system access, and is widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. Signal stability, high accuracy, fast response, long life, short polarization time
2. Industrial Sensors
3. The shell is designed with explosion-proof and explosion-proof structure
4. Support 4-20mA standard signal or directly enter the DOS system
5. Sensor face-down design to ensure good contact with gas
6. The line inlet adopts explosion-proof and waterproof connector
7. With display and alarm functions
Principle
Gas detector detects the gas concentration in the air through Electrochemical sensor. When the concentration reaches or exceeds the preset alarm point, the controller triggers the sound and light alarm. Output signal is 3-wire 4~ 20mA or 4-wire RS485, which can be connected to an external system for monitoring.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
Explosion-proof certificate number: CNEx16.0449, explosion-proof mark: Exd ⅱ C T6 Gb
Steps
1. Wall-Mounted Installation Tester
2. Connect DC24V +/- 10% Power Supply
3. Connect the monitoring system through 4~ 20mA or RS485 Output signal
4. Set the alarm point (such as nitrogen dioxide low alarm point 5ppm)
5. Start the equipment for Gas detection
Notice
• Operating Environment Temperature: -20 ℃~ 50 ℃, Humidity: 0-95% RH (non-condensing)
• Maximum power consumption is 3W, ensure power matching
• Relay output is passive, full load Power does not exceed 1kW
• Make sure the Sensor faces down when installing to optimize gas contact
• Regularly check the operating status of the equipment and the alarm function
