GQQ5 smoke sensor, smoke sensor mine, GQQ0.1 smoke sensor, KGQ-1 skin ..

GQQ5 smoke sensor, smoke sensor mine, GQQ0.1 smoke sensor, KGQ-1 belt 1. Overview GQQ5 smoke sensor smoke sensor is mainly used to monitor coal mine due to mechanical friction, cable fever, other causes of spontaneous combustion coal seam fire. The product is intrinsically safe mine, can be installed in the coal mine belt transportation lane, electromechanical caverns, mined-out area and working face. The sensor can be connected with power means light and sound alarm devices for alarm and power control; also available with a variety of production, supporting the use of safety monitoring systems. 1.1 implementation of the standard 1.2 Model and meaning: 1.3 Explosion-proof type: intrinsically safe. 1.4 Explosion-proof mark: "ExibI Mb". 1.5 Work: continuous work. 1.6 Dimensions: Φ132mm × 148mm. 1.7 Safety parameters Maximum input voltage Ui: 12.0V; Maximum input current Ii: 1.4A; maximum internal inductance Li: 0mH; maximum internal capacitance Ci: 27pF. 2. Environmental conditions 2.1 environment a) Ambient temperature: (0 ~ 40) ℃; b) Humidity: ≤98%; c) atmospheric pressure: (80 ~ 116) kPa; d) wind speed: ≤8m / s. 2.2 Transport and storage conditions a) Temperature: (- 40 ~ 60) ℃; b) Vibration: ≤50m / s2; c) Impact: ≤500m / s2. 3. Main function and technical parameters 3.1 Rated working voltage: 12V.DC. 3.2 Working current: ≤150mA. 3.3 output signal format of the active switching outputs: output high level should not be less than 5V (when current is 2mA); at low output state, the output low should not be higher than 0.5V. 3.4 sensitivity and response time when smog depth of 5% obs / m, the sensor should be action, and the response time should be less than 20s. 4. How it works: After connecting 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, the relay is closed. Achieve automatic fire protection or smoke. Maintenance 1, during use, should pay attention to whether the abnormal operating state inspection apparatus. 2, meets the requirements of the surrounding environment. 3, the fasteners, locking devices, grounding devices without loosening off phenomenon. Denway Jining Mining Equipment Co., Ltd. is located in Jining City, Shandong Province, Tang Industrial Park, new and old customers call to plant inspection.
