BRKM-P Overview
DIFFERENTIAL PRESSURE SENSING QUARTZ CRYSTAL RESONATOR BLOCK BRKM-P APPLICATIONS BRKM-P is a quartz crystal resonator assembly, which consists of a measuring and a reference quartz crystal, both packaged in a rectangular enclosure. The resonance frequency varies with pressure-induced stress. BRKM-P is designed as a ponent for precision electronic differential pressure transducers, manometers and controllers with a...
