Overview
GT-H10-O2 Fixed Gas Alarm is a HUIRUIPU brand equipment for detecting oxygen concentration in the air. When the oxygen 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 ensure the safety of life and property. This product adopts industrial grade Sensor and explosion-proof structure design of die-cast aluminum shell, Sensor down design to ensure good contact, 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. It has the characteristics of long life, high Sensitivity, low drift, stable and reliable work.
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. Adopt flameproof design, suitable for hazardous conditions in zones 1 and 2.
Principle
The alarm detects the oxygen concentration in the environment through the built-in industrial-grade Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and displayed on the display in real time. When the detected oxygen concentration reaches or exceeds the preset low alarm point (19.5% VOL) or high alarm point (23.5% VOL), the controller triggers an audible and visual alarm, and can link the relay output signal to alert personnel and initiate relevant safety measures.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
