Overview
GT-H10 fixed gas alarm is used to detect the concentration of flammability gas or Miscellaneous toxic and harmful gas in the air. When the concentration reaches or exceeds the preset alarm value, the controller will issue a sound and light alarm, and remind to take safety measures in time to prevent explosions and poisoning accidents, so as to ensure the safety of life and property. This product adopts industrial grade Sensor, the instrument shell adopts a die-cast aluminum shell designed with an explosion-proof and explosion-proof structure, and the groove design of the upper cover can lock the shell. The front of the Sensor is designed as a downward structure to ensure that the Sensor is in good contact with the gas. The inlet is made of an explosion-proof waterproof connector.
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 H2S hydrogen sulfide) in the air through an industrial-grade Sensor. When the detected gas concentration reaches or exceeds the preset low alarm value or high alarm value, the controller will trigger a sound and light alarm, and transmit the alarm signal to the upper system through relay output or various signal output methods (such as 4~ 20mA, RS485, etc.) to remind personnel to take safety measures.
Applications
Metallurgy, petroleum, chemical industry, municipal administration
