Overview
The intelligent nine in one gas detection module can simultaneously detect the concentration information of 9 gases, match gas sensors with different principles, read various parameters through standard Modbus RTU communication protocol, and can also synchronously output three wire 4-20mA current signals. It can communicate in real-time with PLC, DCS and other equipment. The product has been calibrated before leaving the factory, which facilitates rapid development and application in the later stage. Connect the aviation plug and the intake/exhaust pipeline, and introduce positive pressure gas for normal detection. The communication status of each channel can be observed in real time through the communication indicator light.

working principle
Intelligent nine in one gas detection moduleBy converting the physical or chemical non electrical signals collected by gas sensors into electrical signals, and then collecting and processing the electrical signals through external circuits. When the gas concentration exceeds the alarm set value, external devices (such as exhaust fans, solenoid valves, sound and light alarms, etc.) can be automatically activated, and remote networking can be achieved to display gas concentration in a centralized manner.
The principle of detection technology varies depending on the type of gas being detected. The main principles include electrochemistry, catalytic combustion, ultraviolet ionization, infrared, thermal conductivity, semiconductors, lasers, etc.
