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 protect life and property safety. The product has the advantages of stable signal, high accuracy, rapid response and long life. It adopts industrial grade Sensor and explosion-proof structure design, supports 4-20mA standard signal output, and can be 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 output or direct access to DOS system
6. Die-cast aluminum shell, upper cover groove design can lock the shell
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 the Sensor. When the detected gas concentration reaches or exceeds the preset alarm value, the controller will immediately issue a sound and light alarm signal to remind the operator to take safety measures in time.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Standards
CNEx16.0449、Exd ⅡC T6 Gb
Steps
