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. 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. Sensor front-down structure design to ensure good contact with gas
4. Explosion-proof and waterproof connectors are used at the line inlet to enhance safety and durability
5. Support three-wire 4~ 20mA or four-wire RS485 signal output
6. With display and alarm light functions, it is convenient for real-time monitoring
7. Response Time is less than 30 seconds, rapid reaction to gas concentration changes
8. Low power consumption, maximum power consumption is only 3W, energy saving and high efficiency
Principle
The GQ-DX101 fixed gas detector works based on the principle of Electrochemical sensor, and detects the concentration of specific gases (such as nitric oxide) in the air through the Sensor. When the gas concentration reaches or exceeds the preset alarm point (such as low alarm point and high alarm point), the controller triggers sound and light alarm, outputs 4-20mA standard signal or transmits data through the RS485 interface to remind the user to take safety measures in time.
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. Connect the signal output line (3-wire 4~ 20mA or 4-wire RS485)
4. Turn on the device and check whether the display and alarm functions are normal.
5. Regularly calibrate Sensors to ensure Measurement accuracy
6. Monitor gas concentration and deal with it when the alarm is triggered
Notice
* Use ambient temperature range -20 ℃~ 50 ℃, Humidity 0-95% RH (no condensation), avoid using beyond the range
* Make sure the Sensor faces down when installing to optimize gas contact
* Regularly check the explosion-proof and waterproof connector to prevent damage to the inlet port
* Avoid use in strong electromagnetic interference environments to avoid affecting signal stability
* Alarm point settings need to be adjusted according to specific gases and standards, do not change at will
* Relay control port is passive output, full load Power does not exceed 1kW, to prevent overload
* Power-off operation during maintenance to ensure safety
