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 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. It supports 4-20mA standard signal or DOS system access. It is widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. Stable signal, high accuracy, rapid response
2. Long lifespan and short polarization time
3. Industrial Sensors
4. The shell is designed with explosion-proof and explosion-proof structure, made of die-cast aluminum
5. Support 4-20mA standard signal or directly enter the DOS system
6. With display and alarm functions
7. Sensor face-down design to ensure good contact with gas
8. The line inlet adopts explosion-proof and waterproof connector
Principle
The detector detects the concentration of flammability gas or toxic and harmful gas in the air through Sensor. When the concentration reaches or exceeds the preset alarm value, the controller triggers sound and light alarm to remind the user to take safety measures. Industrial grade Sensor is used to ensure detection accuracy and Response speed, and the signal output is 4-20mA standard signal or RS485 interface.
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 DC24V +/- 10% power supply
3. Connect the signal output line (3-wire 4~ 20mA or 4-wire RS485)
4. Wait for the polarization to complete after turning it on.
5. Monitor gas concentration and deal with it in time when alarming
Notice
• Ambient Temperature: -20~ 50 ℃
• Environmental humidity: 0~ 95% RH, no condensation
• Make sure the Sensor faces down when installing
• Regularly check whether the alarm function is normal
• Avoid use in out-of-range environments
• Power supply voltage must be kept within DC24V +/- 10% range
