GWD90 temperature sensor, a temperature sensor belt, GWD100 mine temperature sensor ..

GWD90 temperature sensor, a temperature sensor belt, GWD100 mine temperature sensor, temperature sensor connected devices GWD90 temperature sensors are used to distinguish coal mine roadway various high temperature, high temperature surface mining, tunneling head and belt conveyor and other field of temperature sensing. Lane can be installed in the coal mine belt transportation, electrical and mechanical caverns, mined-out area and working face. 1.1 Implementation of the standards: Q / HFT12-2012. 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: 150mm × 62mm × 45mm, weight ≤1Kg. 1.7 related equipment: KHP197-Z. 1.8 Safety parameters Maximum input voltage Ui: 12.0V; Maximum input current Ii: 80mA; Maximum internal inductance Li: 660μH; maximum internal capacitance Ci: 37.0pF. 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: 12VDC; maximum operating current ≤50mA. 3.2 Operating Temperature: 30 ℃ ~ 90 ℃ continuously adjustable, action basic error ± 2 ℃. 3.3 Response time: ≤30s; 3.4 output signal: a group of normally open contacts. 3.5 operational performance: During normal operation, the sensor output normally open contacts open; when the measured temperature exceeds the operating temperature, the sensor output normally open contact closure. 3.6 sensor with digital display, display resolution is 0.1 ℃ 4. works GWD90 temperature sensor temperature sensing element is LM35, when the measured temperature exceeds the operating temperature, the sensor output normally open contact closure. "Super warm" indicator light, the host performs relay released, ultra-temperature protection, language also issued an alarm signal. Buttons can be protected by setting the temperature at different values. Ultra-temperature protection. Maintenance 1 during use, should pay attention to whether the abnormal operating state inspection apparatus. (1) meets the requirements of the surrounding environment. (2) fasteners, locking devices, grounding devices without loosening off phenomenon. Surface temperature sensor 2 Notes (1) The non-coal dust accumulation sensor to be cleaned regularly to prevent reduce monitoring sensitivity; (2) device and then finished after mating equipment line, you should check the connections are correct, with or without bobble and short circuit, grounding device should be solid. Do not use (3) Install megger between the inlet and outlet resistance, in order to avoid damage to the internal components, for measuring the inlet and outlet white resistance multimeter measurements. Main: safety monitoring system and supporting sensors, portable security detection equipment, protective life-saving equipment, mining equipment and related accessories.
