Evaluation of Uncertainty of Indication Error for Dust Concentration Transducer in a Coal Mine
Dust concentration transducer is one of important sensing devices in supervision system of coal mine safety,It plays an important role in avoiding coal dust explosion and protecting workers'health,regular inspection is required to ensure the accuracy of its monitoring results.To evaluate the quality of laboratory test data,this Paper provides an overview of method and procedure for evaluation of uncertainty of indication error for dust concentration transducer used in coal mine,according to the standard requirements,the uncertainty of different measuring points is given,the experimental results show that the laboratory test results of indication error are reliable and meet the requirements.
