Overview
GQ-DX101 Fixed Gas detector is a new type of detector developed by BOSEAN brand combined with years of Gas detection experience. It is used to detect the concentration of flammability gases or 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 ensure the safety of life and property.
This product has the advantages of stable signal, high accuracy, fast response, long life, short polarization time, etc. It adopts industrial-grade Sensor and explosion-proof structure design, supports 4-20mA standard signal output, and can be widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. Industrial Sensor to Ensure detection accuracy and Stability
2. Die-cast aluminum shell with explosion-proof and explosion-proof structure design
3. The upper cover groove design can lock the shell, and the front-down structure of the Sensor ensures good gas contact
4. The line inlet adopts explosion-proof and waterproof connector
5. Support three-wire 4-20mA or four-wire RS485 signal output
6. With display and alarm light functions
7. Response Time Less than 30 seconds
8. Maximum power consumption is only 3W, energy saving and high efficiency
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 instrument adopts 4-20mA standard signal output or RS485 communication mode, which can transmit the detection data to the monitoring system.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
Explosion-proof certificate number: CNEx16.0449, explosion-proof mark: Exd ⅱ C T6 Gb
Steps
1. Operating voltage DC24V +/- 10%
2. Select the Wall-Mounted installation location
3. Connect power cord and signal output line
4. Wait for the instrument to initialize after power on.
5. Observe the display screen to confirm that the instrument is working normally
6. Set alarm parameters (low alarm point 5ppm)
7. Regularly check the operating status of the instrument
Notice
• Use ambient temperature range -20 ℃~ 50 ℃, Humidity 0-95% RH (no condensation)
• Make sure the front of the Sensor is facing down when installing to ensure good gas contact
• Regularly calibrate instruments to ensure Measurement accuracy
• Avoid use in strong electromagnetic interference environments
• Relay output is passive relay, full load Power does not exceed 1kW
• Cut off the power supply during maintenance to ensure safe operation
