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 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. 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 enter the 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. 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. 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
The detector detects the concentration of flammability gas or toxic and harmful gas in the air through the Sensor. When the gas concentration reaches or exceeds the preset alarm value, the controller will trigger the sound and light alarm system to remind the user to take safety measures in time.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
CNEx16.0449、Exd ⅡC T6 Gb
Steps
1. Wall-Mounted Detector
2. Connect DC24V +/- 10% power supply
3. Connect three-wire 4~ 20mA or four-wire RS485 signal output line
4. Wait for the polarization to complete after the device is powered on.
5. Detector automatically starts gas concentration detection
Notice
• Working ambient temperature range -20~ 50 ℃
• Environmental humidity range is 0~ 95% RH without condensation
• Maximum power consumption is 3W
• Response Time Less than 30 seconds
• Make sure the Sensor faces down when installing to ensure good gas contact
• The explosion-proof and waterproof connector needs to be installed correctly at the inlet.
