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 gases or Miscellaneous toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value, the controller will issue a sound and light alarm to remind safety measures in time to prevent explosions 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. It can output 4-20mA standard signal or directly connect to DOS system. It is widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. Industrial Sensor to Ensure detection accuracy and Stability
2. The shell is designed with explosion-proof and explosion-proof structure, which meets explosion-proof standards
3. Sensor face-down design to ensure good contact with gas
4. The line inlet adopts explosion-proof and waterproof connector
5. It has the advantages of stable signal, high accuracy, fast response, long life and short polarization time
6. Support three-wire 4~ 20mA or four-wire RS485 signal output
7. Equipped with display function and alarm light
Principle
Electrochemical sensor detects the specific gas concentration in the air. When the gas concentration reaches or exceeds the preset alarm value, the controller will trigger the sound and light alarm device to remind the user to take safety measures in time. The detection signal can be transmitted to the monitoring system through 4-20mA standard signal output or RS485 interface.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
Explosion-proof certificate number: CNEx16.0449, explosion-proof mark: Exd ⅱ C T6 Gb
Steps
1. Select the Wall-Mounted installation location
2. Connect DC24V +/- 10% Power Supply
3. Connect the signal output line (3-wire 4~ 20mA or 4-wire RS485)
4. Check the normal operation status of the equipment
5. Set alarm parameters according to requirements
Notice
• Working ambient temperature range -20 ℃~ 50 ℃
• Environmental humidity range 0-95% RH (non-condensing)
• Make sure the Sensor is installed face down to ensure the detection effect
• Confirm that the explosion-proof and waterproof connector is firmly installed before use
• Regularly check the operating status of the equipment and the alarm function
The maximum power consumption is 3W, please ensure a stable power supply
