Overview
GT-H10-PH3 Fixed Gas Alarm is a HUIRUIPU brand for detecting phosphating hydrogen (PH3) gas concentration 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 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 of die-cast aluminum shell, Sensor front down design to ensure good gas contact, and equipped with explosion-proof waterproof connector, 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 concentration of specific gases (such as phosphating hydrogen) in the air through the built-in industrial grade Sensor. When the detected gas concentration reaches or exceeds the preset low alarm point or high alarm point, the controller will trigger the sound and light alarm signal, and the alarm information can be uploaded to the control system or cloud platform through relay output or various signal output methods (such as 4~ 20mA, RS485, IoT signal), so that timely safety measures can be taken.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
