Sensors for monitoring physical and chemical parameters of mine atmosphere equipped with a digital communication interface

摘要

The article presents a series of types of sensors for measuring physical and chemical parameters of mine atmosphere, designed to co-operate with the SMP-NT/A system. The functional features of the sensors were described, with the focus on their modular structure and state-of-the-art structure of measuring chambers. The possibility to monitor several parameters at a time was pointed out, along with the possibility to extend this sensor family by devices for measuring the concentration of other gases.
