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 flammability gas or toxic and harmful gas in the air. When the concentration reaches or exceeds the preset alarm value, the controller will issue sound and light alarm, timely reminder to take safety measures, prevent explosion and poisoning accidents, and protect life and property safety. The product has the advantages of stable signal, high accuracy, rapid 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. Stable Signal, High Accuracy, Fast Response, Long Life and 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. Upper cover groove design can lock the shell
Principle
The GQ-DX101 fixed gas detector detects the concentration of flammability gas or toxic and harmful gas in the air through the Sensor. When the gas concentration is detected to reach or exceed the preset alarm value, the controller triggers the sound and light alarm to remind the user to take safety measures in time to prevent explosions and poisoning accidents.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
CNEx16.0449、Exd ⅡC T6 Gb
Steps
1. Install the detector in the wall-mounted position
2. Connect the power supply (DC 24V +/- 15%)
3. Connect the signal output line (3-wire 4~ 20mA or 4-wire RS485)
4. Start the device and wait for the polarization to complete
5. Monitor gas concentration and take appropriate safety measures when the alarm is triggered
Notice
• Working ambient temperature range -10~ 40 ℃
• Environmental humidity range of 0~ 95% RH, no condensation
• Power supply voltage 24V +/- 15%
• Pay attention to the front facing of the Sensor when installing to optimize gas contact
• Regularly check the status of the equipment to avoid using it under conditions exceeding specifications
