GQQ01 smoke sensor

GQQ0.1 smoke sensor Jinan, China Coal Mining Equipment Co., Ltd. is a professional manufacturer, good product quality, service and good attitude, delivery speed, you are welcome to establish long-term partnerships. Original KGQ-1 type smoke sensor, mining smoke sensors, smoke sensors offer, GQQ0.1 smoke sensors, mine KGQ-1 type smoke sensor, smoke sensor GQQ0.1 Shandong, Jinan smoke sensor, smoke sensor smoke quotes GQQ0.1 Sensor Overview: GQQ0.1 (original model KGQ-1) smoke sensor is mainly used for rubber, coal mine, coal dust, etc. from the heat due to friction or other causes smoke monitoring. GQQ0.1 smoke sensor principle: After connected to the power, the green light, to be stable for 10 minutes, the green light off the red light, said detection probe end thermal stabilization time, the sensor enters the detection state. When a small amount of smoke into the smoke chamber, the red light flashes, while controlling the three MOSFET, output low, smoke fault indication light, the relay is closed. Achieve automatic fire protection or smoke. At the same time the speaker "X number belt smoke," the language of the alarm. Host achieve protection and blocking, this time to restart, need troubleshooting, and click the stop button to unlock, and then press the start button, the belt conveyor can be run from the car. GQQ0.1 smoke sensor using ambient atmospheric pressure:? 80-106kPa; ambient temperature is not higher than + 40 ℃, not lower than 20 ℃; ambient air relative humidity less than 95% (20 ± 5 ℃); in the absence of significant without enough to corrode metal and damage the insulation of gas and vapor environment;; in the absence of a liquid immersion drip and place pan and place of shock and vibration. GQQ0.1 smoke sensor Product Type: Mine explosion-proof type is intrinsically safe, explosion-proof mark: "ExibI". Model GQQ 0.1 action value: 0.1mg / m3 works: GQQ0.1 gas sensing smoke sensor measurement object: smoke GQQ0.1 smoke sensor technology allows the performance of the grid voltage fluctuation range: -25% ~ + 10%; Operating voltage: DC12V Working current 150mA; recovery time: more than 5 seconds. Transmission distance sensor to a host of not less than 1000m, (single cross-sectional area of ??1.5mm2) e, 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 When the sensitivity and response time of the sensor when the smoke alarm ≤0.5V concentration of 0.1mg / m3, the sensor response time ≤30s. Sensor sensitivity class II. Dimensions: 175 × 100 × 145; Weight: 0.8kg.
