The probe of capacitive vortex flow sensor is composed of a pair of differential capacitors. The vortex force generated by the vortex generator alternates between the two sides of the probe, so that the differential capacitance within the probe changes in the difference, converted by the amplifier into a flow electric pulse signal.
Excellent internal structure of the probe has good vibration resistance and can measure the minimum flow. Probe capacitance plate substrate using professional ceramics molded at high temperatures of more than 1,000 degrees, so high-temperature characteristics, the core components of the process, structure and domestic and foreign detection components have essential differences, higher reliability.
Intelligent sensor with gas, liquid versatility, pass band automatic tracking, no potentiometer or toggle switch to adjust the frequency band and sensitivity, no zero drift, free range setting, the real realization of the field without debugging. The circuit has suppression effect on different vibration frequencies, enhancing anti-vibration performance and linearization function.
