| PRESSURE SENSING QUARTZ CRYSTAL RESONATOR RKMA-P APPLICATIONS RKMA-P is a quartz crystal resonator which is packaged in a rectangular enclosure. The resonance frequency varies with the pressure-induced stress. The crystal unit is designed as a precision electronic pressure sensor for transducer, manometers, and controllers with a frequency output for the conversion of the absolute pressure to frequency. FEATURES - High resolution and accuracy - Long term quartz crystal stability - Wide temperature range (-55...+80 C) - Low power consumption Suitable for precision pressure equipment ELECTRICAL CHARACTERISTICS (at normal climatic conditions) / OPERATING CONDITIONS PARAMETERS Model Frequency range, fO Resonance resistance typ./max., Rr Drive Level max., DL Insulation Resistance min.
