Magnetically controlled gas detectors

摘要

Non-contact magnetic, optical like infrared or RF communication elements can be used to control various operational aspects, or parameters of a gas detector (12). The detector (12) can be placed in a low current, or sleep, mode wherein the operational life-time, e.g. battery lifetime, is not reduced by the duration of the sleep mode. Instructions can be coupled to the detector (12) magnetically, optically, or via RF to alter set points or other operating parameters. Information as to bump tests can also be coupled to the detector (12).
