Operating principle of the electronic gas density sensor The constant resonant frequency of a quartz tuning fork under vacuum is compared with the resonant frequency of an identical quartz s ituated in the sample gas. The difference in the resonant frequency Functional diagram is proportional to the density of the sample gas. This difference is processed into an output signal. Finit element stress analysis of an oscillation tuning fork quartz in vacuum Electrical connections and wiring diagram Wiring diagram 879X.XX.XXXX.XX Number of microswitches according to application (max. 3) connect...
