APPLICATION & SELECTION
Methane monitoring with machine power-off control
This system is intended for methane monitoring on coal mining, tunnelling and drilling machinery. Its controller and compatible sensor provide concentration display, alarms and power-off/reset control. Selection should consider the complete controller–sensor configuration rather than the controller alone.
What to confirm before ordering
Confirm the machine power supply, compatible sensor, communication cable arrangement, alarm requirements and power-off interface. Ask for the wiring documentation and current certificates for every component in the proposed system.
Request model-specific documentation
Email antaiair@163.com with the model, gases to be monitored, machinery, supply voltage, interfaces and expected quantity. Ask for the current datasheet, applicable certificates and product support information.
Specifications are reproduced from the supplied Chinese catalogue. Installation and maintenance must follow current manufacturer documentation and the requirements of the intended site.
