Product Details
Overview of carbon monoxide sensor products for coal mines:
The GTH1000 (B) coal mine carbon monoxide sensor is a high-precision instrument for continuously detecting the concentration of carbon monoxide in the mine. Sensors can measure and display the concentration of carbon monoxide in the mine in real-time, and generate an audible and visual alarm signal based on the concentration value, and output a 485 digital signal corresponding to the concentration of carbon monoxide. Sensors can predict and predict early fire and explosion accidents caused by various factors such as coal seam spontaneous combustion, mechanical and electrical equipment, and transportation belt accidents in mines with gas and coal dust explosions. In addition to being used in conjunction with our company's KJ70X coal mine monitoring system, sensors can also be independently used in various mining fire detection systems.
Product parameters of carbon monoxide sensors for coal mines:
1. Working voltage: (9-24) V;
2. Working current: ≤ 80mA;
3. Range: (0-1000) × 10-6 CO;
4. Output signal:
a) Frequency: 200Hz~1000Hz, 5Hz~15Hz;
