GWD75 / (B) a temperature sensor

GWD75 (B) temperature 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. Temperature sensors, sensors, speed sensors, coal-bit sensors, carbon monoxide sensors, gas sensors, deviation sensors, smoke Sensor Overview I. Purpose and scope of application of this product is flameproof and intrinsically safe, marked as: ExibI; suitable for coal mine containing dust and explosive gas, and KHP128 belt protection devices supporting the use of a host of belt machine motor over-temperature protection, over-temperature or as a watering solenoid temperature probe purposes. When properly installed, power indicator light enters the detection state, the output is high; when the detected temperature exceeds a predetermined value, the output low for fault conditions and accompanied by "XX No. Belt overtemperature" the voice alarm the belt stop . Internal setting 45 ℃, 55 ℃, 65 ℃, 75 ℃ 4 files. GWD75 temperature sensor mining intrinsically safe electrical equipment, mainly for the main conveyor belt drive roller and the frictional heat, electrical, temperature or other causes fever reducer shell produced for testing can also be used for other electrical equipment The temperature detection. SIGN is IxibI power indicator light enters the detection state, if the light is off operation, fault state and accompanied by "XX No. Belt overtemperature" the voice alarm. Second, models and specifications G: Sensor W: temperature D: Temperature Measurement IC 75: Measurement range B: number three, the main features of the sensors are small, rugged, good sealing, long life, low failure rate; 2 with an integrated temperature sensing element, the sensor has good linearity error is small, sensitive, accurate action, without tripping; 3, simple circuit, high integration, easy installation and maintenance; 4, with test button easy for users to verify sensor performance; 5, has a working status indication and alarm status indication. Fourth, the use of environmental conditions 1, ambient temperature: -10 ℃ ~ + 40 ℃; 2, altitude ≤2000m; 3, atmospheric pressure: 80 ~ 106Kpa; 4, the average monthly ambient air relative humidity less than 95% (25 ℃ ); 5, have gas and coal dust explosion hazard; and 6, in the absence of damage to the insulation of gas or vapor environment; 7, no dripping water and other liquid intrusion of 8 places, no significant vibration and shock of the place ; 9, pollution degree 3, install-category 1; Fifth, the main technical parameters 1, explosion-proof type: Mine intrinsically safe, marked as: ExibI 2, shell protection grade: IP54 3, intrinsically safe parameters: Working voltage 8V-12V 15mA operating current weight 0.5Kg 4, introduced directly into the way: the number of outlet ports: one, the introduction of cable diameter: φ6 ~ φ10mm 5, the sensor and the host connection cables are not more than 1000m; distributed capacitance ≤0.1uF / km; Distribution inductance ≤1mH / km; 6, related equipment:. KHP136-Z Mine explosion-proof and intrinsically safe type belt conveyor integrated protection control box a proof type: Mine explosion-proof and intrinsically safe, explosion-proof mark: Exd [ib ] I; 7, the temperature measuring range: 10-90 ℃, error of + 5%
