WebIntelligent Heat Detectors SIGA-HFS & SIGA-HRS Overview Signature Series Model SIGA-HFS and SIGA-HRS Intelligent Heat Detectors gather analog information from their fixed temperature and/or rate-of-rise heat sensing elements and converts it into dig-ital signals. The detector’s on-board microprocessor measures and analyzes these signals. http://dictionary.sensagent.com/DICTOGRAPH/en-en/ WebThe term heat detectorcan be used for a specific type of detection system whose sensor element is a metal that normally melts at 70°C/158°F. This system is known as fusible plug system, based on its operating principle that includes a compressed air line in which the fuse plugs are installed to monitor a specific area. おいかんむりの漢字 一覧
