Abstract: The multi parameter sensor for mining gas drainage is suitable for places with gas and coal dust explosion hazards in coal mines, achieving pipeline parameter monitoring (including differential pressure, temperature, gas concentration, etc.). This article provides a detailed introduction to the uncertainty evaluation of differential pressure, temperature, and gas concentration indication errors of multi parameter sensors for mining gas drainage through specific examples.

Key words: multi-parameter sensor for mine gas drainage; differential pressure; temperature; gas concentration; uncertainty evaluation
