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.

PACKAGE DIMENSIONS
Four basic package variants of RKMA-P are available:
RKMA-P-1: basic model for direct fastening on the transducer case.
RKMA-P-2: Small size variant of RKMA-P-1 (see “Operation Conditions” table).
RKMA-P-3: With additional cover, glued to surface, for temperature isolation.
RKMA-P-4: With metal connecting pipe, through which the pressure is guided.
