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. Signal stability, high accuracy, fast response, long life, short polarization time
2. Industrial Sensors
3. The shell is designed with explosion-proof and explosion-proof structure
4. Support 4-20mA standard signal or directly enter the DOS system
5. Sensor face-down design to ensure good contact with gas
6. The line inlet adopts explosion-proof and waterproof connector
7. Upper cover groove design can lock the shell
Principle
The gas detector detects the concentration of flammability gases or toxic and harmful gases in the air through the Sensor. When the detected gas concentration reaches or exceeds the preset alarm value, the controller will trigger a sound and light alarm to remind the user to take safety measures.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
CNEx16.0449、Exd ⅡC T6 Gb
Steps
1. Installation: Wall-Mounted Installation method
2. Connection: use three-wire 4~ 20mA or four-wire RS485 signal output
3. Power supply: Connect to DC 24V +/- 15% power supply
4. Settings: Measurement range and alarm points are configured according to the gas parameter table
5. Operation: The equipment works under -10~ 40 ℃ temperature and 0~ 95% RH Humidity environment
Notice
• Working ambient temperature range -10~ 40 ℃
• Environmental humidity is 0~ 95% RH to ensure no condensation
• Maximum power consumption is 3W, and the power supply must meet the requirements of DC 24V +/- 15%
• Make sure the Sensor faces down when installing to optimize gas contact
• Use explosion-proof waterproof connector for incoming connection
• Response Time less than 30 seconds, need to check equipment performance regularly
