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 flammable or toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value, sound and light alarm will be issued to remind safety measures to prevent explosion and poisoning accidents and ensure the safety of life and property. The product has the advantages of stable signal, high accuracy, fast response, long life and short polarization time. It adopts industrial grade Sensor and explosion-proof structure design, supports 4-20mA standard signal output, and 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 output 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. With display and alarm functions
Principle
Electrochemical sensors detect the concentration of specific gases in the air. When the concentration reaches or exceeds the preset alarm point, the controller triggers the sound and light alarm to remind the user to take safety measures in time. The signal output adopts three-wire 4-20mA or four-wire RS485 mode, which can be integrated into the monitoring system.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
Explosion-proof certificate number: CNEx16.0449, explosion-proof mark: Exd ⅱ C T6 Gb
Steps
1. Wall-Mounted Detector
2. Connect DC24V +/- 10% Power Supply
3. Configure signal output (3-wire 4-20mA or 4-wire RS485)
4. Set the alarm point (such as chlorine low alarm point 5ppm)
5. Start the equipment for Gas detection
Notice
* Use ambient temperature range -20 ℃~ 50 ℃, Humidity 0-95% RH (no condensation)
* Ensure Sensor is mounted face down to optimize gas contact
* Relay output is passive relay, full load Power does not exceed 1kW
* Periodically check Indication Errors to be within +/- 3% FS
* Follow explosion protection requirements and avoid use in non-specified environments
