Overview
GT-H10-EX fixed gas alarm is a HUIRUIPU brand for detecting the concentration of flammability gas in the air. When the gas concentration reaches or exceeds the preset alarm value, the controller will issue a sound and light alarm to remind safety measures to prevent explosion accidents and protect life and property safety. The product adopts industrial-grade Sensor and die-cast aluminum shell with explosion-proof and explosion-proof structure. The Sensor is designed face-down to ensure good contact and 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 and 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) signal output and Lora/4G IoT signal output, which can be uploaded 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 flammability gas concentration in the air through the built-in industrial-grade Sensor. The Sensor converts the detected gas concentration signal into an electrical signal, which is processed by the internal circuit and compared with the preset alarm threshold. When the concentration reaches or exceeds the low alarm point or the high alarm point, the controller will trigger an audible and visual alarm, and output an alarm signal through a relay or communication interface.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Steps
1. Install the fixed detector at the designated location and connect the power supply and signal cable.
2. Use infrared remote control for parameter setting, including alarm point, range, etc.
3. After power on, the device performs self-test to observe whether the display and indicator light status are normal.
4. The equipment enters the normal working monitoring state and displays the gas concentration in real time.
5. When the concentration exceeds the standard to trigger the alarm, take safety measures according to the plan.
6. Regular use of standard gas for calibrating and maintenance.
Notice
• Please install, debug and maintain by professionals.
• Installation location should ensure that the Sensor can be fully contacted with the gas to be tested to avoid occlusion.
• Regularly check the operating status of the equipment and whether the alarm function is normal.
• Avoid use in environments with strong electromagnetic interference, corrosive gases or extreme temperature and humidity.
When performing maintenance or calibrating, ensure that the environment is safe and follow relevant safety procedures.
• Pay attention to the detection gas type and range corresponding to the product model, and do not use it beyond the range.
