Mining Inreinsically Safe Velocity Sensor for Belt Conveyor
1.Summary It is suitable for the detection of speed protection signal of belt conveyor protection device in coal mine in the environment of explosive gas (ch4) in coal mine, as well as in open-pit coal mine, coal preparation plant and other workplaces. 2.Main technical parameters Intrinsically safe parameter :Ui:DC12.5V;Ii:13mA;Ci:0μF;Li:0mH. Measuring range :0~5m/s Basic and linear error :±2.0% Frequency response range:20Hz~5kHz
3.Regular service conditions Ambient temperature is 0ºC~+40ºC ; height above sea level not exceeding 2000m(80kPa~110kPa); Ambient air relative humidity not greater than 98%(25ºC); Mine containing methane explosive mixture; Where there is no significant shaking or shock vibration; A place where dripping can be prevented in an environment where insulated gases or vapours are not destroyed. Worst storage and transportation conditions High temperature Low temperature Average relative humidity.
