Overview
The GT-H10-NO2 Fixed Gas Alarm is a HUIRUIPU brand device for detecting the concentration of nitrogen dioxide (NO2) 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 poisoning accidents and protect life and property safety. The product uses industrial-grade Sensor and die-cast aluminum housing with explosion-proof and explosion-proof structure, which is designed to be safe and reliable, and is suitable for use in dangerous places.
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. Sensor fault self-test, two-level concentration alarm and relay output function.
5. Provide LCD/digital display and working status indication.
6. Support zero point 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 concentration of specific gases (such as nitrogen dioxide) in the air through the built-in industrial-grade Sensor. The Sensor converts the 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 preset low or high alarm value, the controller triggers an audible and visual alarm, and can output a control signal (e.g. through a relay or communication interface) to achieve early warning and safety linkage.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
Steps
1. According to the installation specifications, fix the alarm in place and complete the electrical wiring.
2. Turn on the power supply, the device starts and performs self-test.
3. Use infrared remote control, no need to open the lid to set parameters (such as alarm point, range, etc.).
4. The equipment enters the normal working state, continuously monitors the gas concentration and displays it on the display screen.
5. When the concentration exceeds the standard, the device emits a sound and light alarm and outputs a signal according to the configuration.
Notice
• Please be sure to install, debug and maintain it by professionals.
• Installation location should ensure that the Sensor can be in good contact with the gas to be tested to avoid occlusion.
• Regularly calibrate and maintain equipment to ensure detection accuracy and reliability.
• Pay attention to the working environment requirements of the equipment and avoid using it beyond the specified conditions (such as temperature, humidity).
Make sure the environment is safe and follow relevant safety procedures before any operation.
