Overview
GQ-DX101-PH3 Fixed Gas detector is a new type detector developed by BOSEAN company 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 a sound and light alarm to remind safety measures in time to 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
5. Support 4-20mA standard signal or directly enter the DOS system
6. Sensor face-down design to ensure good contact with gas
7. The line inlet adopts explosion-proof and waterproof connector
8. Die-cast aluminum shell, upper cover groove design can lock the shell
Principle
The Gas detector detects the target gas concentration in the air through the Sensor. When the concentration reaches or exceeds the preset alarm value, the controller triggers the sound and light alarm. The instrument adopts industrial grade Sensor to ensure the detection accuracy and Response speed. The signal output supports three-wire 4-20mA or four-wire RS485, which can be integrated into the monitoring system.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
CNEx16.0449、Exd ⅡC T6 Gb
Steps
1. Installation equipment: Wall-Mounted installation
2. Connect power supply: connect to DC 24V +/- 15% power supply
3. Signal connection: Select three-wire 4-20mA or four-wire RS485 output
4. Set the alarm point: set the corresponding alarm value according to the gas type (such as PH3 phosphating hydrogen low alarm point 5ppm)
5. Start detection: the device starts to monitor gas concentration
6. Monitoring alarm: When the concentration exceeds the limit, the sound and light alarm is automatically triggered
Notice
• Working ambient temperature range -10~ 40 ℃
• Environmental humidity of 0~ 95% RH, avoid condensation
• DC power requirements 24V +/- 15%
• Make sure the Sensor faces down when installing to optimize gas contact
• The maximum power consumption is 3W, and it is necessary to ensure stable power supply
• Response Time is less than 30 seconds and requires regular calibrated maintenance
• The explosion-proof mark is Exd ⅱ C T6 Gb, which needs to be used in an explosion-proof environment
