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 a sound and light alarm to remind the safety measures to be taken in time to prevent explosion and poisoning accidents and ensure the safety of life and property. 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. Industrial Sensor to Ensure detection accuracy and Stability
2. The shell adopts die-cast aluminum shell designed with explosion-proof and explosion-proof structure, and the upper cover groove is designed to lock the shell
3. The front of the Sensor is designed as a downward structure to ensure good contact with the gas
4. Explosion-proof and waterproof connectors are used at the line inlet to enhance safety and durability
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, compatible with a variety of systems
7. Equipped with display and alarm light functions for real-time monitoring
Principle
The GQ-DX101 fixed gas detector works based on the principle of Electrochemical sensor to detect specific gas concentrations in the air. When the gas concentration reaches or exceeds the preset alarm point, the controller triggers an audible and visual alarm to remind the user to take safety measures in time. The detector transmits concentration data in 4-20mA or RS485 format through the signal output module, supporting remote monitoring and System integration.
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%, connect power
2. Select the Wall-Mounted installation location according to the Installation method
3. Use explosion-proof waterproof connector to access the line to ensure sealing
4. Start the device and check whether the display and alarm functions are normal
5. Set the alarm point (e.g. oxygen: low 19.5% vol, high 23.5% vol)
6. Monitor gas concentration, Response Time is less than 30 seconds
7. Regular Maintenance to Ensure Sensor and Housing Cleanliness
Notice
* Use ambient temperature range -20 ℃~ 50 ℃, Humidity 0-95% RH (no condensation), avoid exceeding the range
* Make sure the Sensor faces down when installing to optimize gas contact
* The relay control port is passive relay output, full load Power does not exceed 1kW
Regularly check the explosion-proof structure and cable inlet to prevent damage
* The alarm point setting needs to be adjusted according to the specific gas type and Measurement range to avoid false alarms or missed alarms
* Follow safety regulations when operating to prevent sparks in flammable and explosive environments
