Description

Online Coal Ash Analyzer DF-5753 Online Coal Ash Analyzer The Online Coal Ash Analyzer (DF-5753) is used for on-line detection, measurement and control of coal ash & finds wide application in coal mines, coal washing plants, coal blending plants, coking plants, coal-fired power plants, steel plants and coal terminal, etc. It is especially suitable for on-line coal ash analysis on the entire belt conveyor during the coal transportation process.
Working principleOn the basis of double energy γ ray absorption method, the coal ash content can be calculated by processing data of the two rays after passing coal attenuation. Technical parametersMeasurement range: 5%~50%Measurement accuracy:. When the ash content is between 0 and 15%, error ≤±0.5%;. When the ash content is between 15% and 30%, error ≤±1.0%;. When the ash content percentage is beyond 30%, error ≤±2.0%;Measurement time: 1~3 minsBelt speed: less than 5m/sParticle size of coal sample: less than 50mmMateriel thickness: 50mm~300mmMeasurement requirement: continuous measurement and without lacking materielEnvironment temperature: -20~45°CControl room temperature: 0~40°CDetector temperature control accuracy: ±0.5°CAnalog quantity output:4-20mAPower: 220V(±10%)50Hz Safety The safety of sealed sources meets the requirements of GB4075. Dose equivalent rate at 1m of instrument surface≤2.5μSv/h meets requirements of radiation protection in GBZ125-2002. It will not harm operator in regular use.
