Carbon monoxide sensor mine GTH1000 Product Name: GTH1000 carbon monoxide sensor mine Industry: Mining CAUTION: repair and intrinsically safe circuits shall not be changed with the intrinsically safe circuit electrical parameters related components, specifications and models! GTH1000 carbon monoxide sensor mine one, mine uses GTH1000 carbon monoxide sensor (hereinafter referred to as the sensor) is to meet the carbon monoxide concentration of coal mine monitoring needs and developed. It can continuously and automatically convert the carbon monoxide standard downhole electrical signal transmission to mating equipment, and has a local display gas concentration, overrun sound and light alarm. Sensor proof test by the state authorities for online examination, can be used with all types of domestic monitoring systems and power meter, gas locking devices supporting wind power, suitable for coal mining face, electromechanical chamber, back to the wind tunnel and other locations stationary use. Second, the model implications, explosion-proof type and mark sensor type is mine intrinsically safe, explosion-proof mark "ExibI Mb". Three, dimensions, quality and materials a) Dimensions: 270 × 155 × 55mm b) Weight: ≤ 1.3kg; c) Housing material: Stainless steel. Fourth, the main features 1. Using new highly integrated single-chip microcomputer and digital circuits, the circuit structure is simple, reliable performance, easy maintenance and debugging. ? 2. Infrared remote control adjustment to achieve the offset, sensitivity, alarm point other features that make adjustment easy and convenient. 3. Increases the sensor power control functions, and to set arbitrary power points, for a multi-purpose machine. 4. Using the new switching power supply, greatly reduce power consumption and increase the transmission distance of the instrument. 5. Increases the fault self-test function, easy to use and maintain. 6. Designed a new high-strength shell structure, enhanced impact resistance of the instrument.
