 APPLICATIONS
Quartz pressure transducer PDTK-P-MS provides the precision pressure measurement of hostile environment with a capability of compensation of a temperature error in an interval of operation temperatures.
The remarkable performance of these transducers is achieved through the use of a precision quartz crystal resonator whose frequency of oscillation varies with pressure-induced stress. A quartz crystal temperature signal is provided a capability to thermally compensate the measured pressure and achieve high accuracy over a broad range of temperatures.
The transducer has a stainless steel bellow or membrane as a separator. The remarkable performance of these transducers is achieved through the use of a precision quartz crystal resonator whose frequency of oscillation varies with pressure-induced stress. A quartz crystal temperature signal is provided a capability to thermally compensate measured pressure and achieve high accuracy over a broad range of temperatures.
