Methane sensor image methane sensor parameters

Methane sensor Image sensor methane sensor parameters Nian Liu Heng Wang mining machine 0537-2164458 13012610363 Description: methane sensor is to meet the needs of our monitoring of underground coal mine methane and developed it can continuously and automatically converts electrical signals into standard underground methane concentration transmission to the associated equipment, and has a local display of methane concentration, after overrun sound and light alarm and power-off function. proof test by the state authorities for online testing, can be used with all types of domestic monitoring system and power meter, wind power gas locking device facilities, suitable for stationary use in coal mining Face, electromechanical chamber, back to the wind tunnel and other locations. The main technical indicators: Measuring range: 0 ~ 4.00% CH4 basic measurement error: 0.00 ~ 1.00% CH4 ± 0.10% CH4 1.00 ~ 2.00% CH4 ± 0.20% CH4 2.00 ~ 4.00% CH4 ± 0.30% CH4 Display: four red LED tube display function: 1 - zero; 2- tone sensitivity; 3 - tone alarm; 4- tune off point; after three 5- POST: Measuring value display (% CH4) Output: signal with a load capacity : 0 ~ 400Ω Alarm: two intermittent sound and light alarm sound intensity> 85dB, light intensity: visibility> 20m alarm point range: 0 ~ 4% CH4 continuously adjustable power point settings: as 0.50,0.75, respectively, 1.00,1.25,1.5,2.0% CH4, respectively corresponding point complex power point lower limit can be set in the range 0-3% CH4. Sampling Method: Diffusion-type; element detection response speed: <30S thermal catalytic component life: One year security parameters: a) μi: 18V (DC) Ii: 70mA b) Ci: 0.08μF li: 0mA Operating voltage: DC9-24V ; Working Current: ≤85mA proof type: Mine intrinsically safe and explosion-proof; proof mark: ExibdI Dimensions: 190 × 114 × 57, Weight: 700g Heng Wang Mining Machinery Co., Ltd.
