Overview
GT-H10-NH3 Fixed Gas Alarm is a HUIRUIPU brand equipment for detecting ammonia (NH3) concentration in the air. When the ammonia concentration reaches or exceeds the preset alarm value, the controller will issue a sound and light alarm to remind to take safety measures to prevent poisoning accidents, so as to 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 to ensure good contact, can be widely used in metallurgy, petroleum, chemical, municipal and other industries.
Features
1. Dust-proof, explosion-proof, anti-static, anti-reverse connection, anti-interference, surge protection functions.
2. Adjustable detection accuracy and range.
3. Long life, High Sensitivity, Low drift, Stable and reliable work.
4. Sensor fault self-test, two-level concentration alarm, with relay output function.
5. LCD/digital display, working status indication.
6. Zero point automatic tracking, temperature automatic compensation, concentration over range protection, 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. Infrared remote control mode, the detector can be adjusted without opening the lid, which is safe and convenient.
9. Pluggable Module Sensor design, convenient for later maintenance.
10. The flameproof design is suitable for use in hazardous conditions 1 and 2.
Principle
The alarm detects the concentration of specific gases (such as ammonia) in the air through the built-in industrial-grade Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and analyzed by the internal circuit. When the detected gas concentration reaches or exceeds the preset alarm threshold, the controller triggers the sound and light alarm device, and can upload the alarm signal to the PLC, DCS or cloud platform through relay output or multiple communication methods (such as 4-20mA, RS485, IoT signal) to alert the operator and connect with Miscellaneous safety equipment.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
