A new methanometer without any calibration

Abstract

The sensor most commonly used for detecting firedamp (methane) and measuring its concentradon in mines is the catalytic sensor, which costs less than an infra-red detector. The convendonal catalytic sensor has two component parts - a detecting element and a compensating element - enclosed in a flameproof reaction chamber. The detector is a filament encased in a pellet of composite material, made up of alumina mixed with powdered metal (palladium or platinum) which acts as an oxidadon catalyst.
