GQQ smoke sensor

GQQ smoke sensor, GQQ smoke sensor manufacturers, GQQ Supplying zmjt02 GQQ smoke sensor smoke sensor Products GQQ smoke sensor intrinsically safe mine for coal mine fire monitoring friction due to mechanical failure, cable heat, coal bed natural causes such as accident, can be installed in the coal mine belt conveyor machine next to easy to heat at a mine belt conveyor protection device smoke protection signal detection purposes. Explosion-proof type mine intrinsically safe explosion-proof mark: ExibⅠ shell protection grade: IP54 GQQ smoke sensor model significance Model: GQQ0.1 Q-- smoke sensor smoke sensor G-- Q-- gas sensing 0.1-- main parameters, action value, 0.1mg / m3 GQQ smoke sensor conditions a) Temperature: 0 ℃ ~ + 40 ℃; b) Humidity: ≤95%; c) atmospheric pressure: (86 ~ 106) kPa; d) altitude less than 2000m; e) Vibration: acceleration 50m / s2; f) Impact: Peak acceleration 500 m / s2; g) coal mine without damage to the insulation of the corrosive gas. h) for hazardous locations explosive mixture of methane, coal dust and the like. i) wind speed: (0 ~ 8) m / s smoke sensor smoke sensor GQQ GQQ structural features small size, light weight, good sealing performance, features easy mounting of the bail convenient and reliable installation, commissioning and maintenance of the sensor. The sensor uses a gas-sensitive probe components, sensitive, reliable, and correct action, outputs a low level signal to achieve the conveyor smoke protection when the measured smoke density ≥0.1mg / m3. GQQ smoke sensor parameters 1, the grid voltage fluctuation allowed range: -25% to + 10%; 2, working voltage: DC12V, working current 150mA; 3, the recovery time: more than 5 seconds. 4, the sensor transmission distance of the host to not less than 1000m, (single cross-sectional area of ??1.5mm2) 5, the output signal of the sensor system shall comply with the provisions of Article 5.3 MT209-1990 and smoking should be detected as (5-10V), smoke alarm ≤0.5V 6, sensitivity and response time GQQ0.1 smoke sensor: When the smoke concentration of 0.1mg / m3, the sensor response time ≤30s. Sensor sensitivity class II. The product has been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other customers receive the praise due to production batch, the specific model is different from the above picture for reference only, contact Our sales staff will be specifically verified.
