Overview
GT-H10-CO2 Fixed Gas Alarm is a HUIRUIPU brand for detecting the concentration of carbon dioxide (CO2) gas in the air. When the detected gas concentration reaches or exceeds the preset alarm value, the controller will issue a sound and light alarm to remind safety measures to prevent accidents and protect life and property safety. This product adopts industrial grade Sensor and explosion-proof structure design of die-cast aluminum shell. Sensor front-down design ensures good contact. It can be widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. With dust-proof, explosion-proof, anti-static, anti-reverse connection, anti-interference and surge protection functions.
2. Adjustable detection accuracy and range.
3. Sensor has the characteristics of long life, high Sensitivity, low drift and stable and reliable operation.
4. Support Sensor fault self-test, two-level concentration alarm, and relay output function.
5. Provide LCD/digital display and working status indication.
6. With zero automatic tracking, temperature automatic compensation, concentration over range protection and multi-point calibrating function.
7. At the same time, it supports two-wire (PowerBus), three-wire (4~ 20mA), four-wire (RS485) and Lora/4G IoT signal output, and can be connected to PLC, DCS and cloud platform.
8. Using infrared remote control, the detector can be adjusted without opening the lid, making it safe and convenient.
9. Sensor design with pluggable module is convenient for later maintenance.
10. Adopting a flameproof design, it is suitable for hazardous conditions in Zone 1 and Zone 2.
Principle
The alarm detects the concentration of carbon dioxide (CO2) in the environment through its built-in industrial-grade Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and analyzed by an internal circuit. When the concentration reaches or exceeds the preset low alarm value (2000ppm) or high alarm value (4000ppm), the controller triggers a sound and light alarm, and can output a signal to an external device to achieve early warning and safety linkage.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
