Kaidi KD Vibrating Fork Level Switch for Liquid and Solid Media

The Vibrating Fork Level Switch is designed using the principle of the damping effect of the medium on the vibrating fork vibration and the piezoelectric effect. The sensing part for detecting the material (liquid) level is composed of the vibrating fork, which has a fixed vibration frequency and amplitude vibration. When the tvibrating fork is subjected to medium damping, the vibrating fork stops vibrating, and the control circuit drives the relay to send out a switch signal.

The product can adapt to the harsh working conditions and work reliably. It is the most widely used product in the material (liquid) level switch instrument.

①With automatic learning function, through the button, without calibration, you can learn different medium densities;

②All metal structure, sturdy and durable;

③The fork body has a large vibration amplitude, which can reach more than 10mm, which can shake off the low-viscosity local hanging material on the induction rod to prevent misoperation;

④The super bright red LED light provides a more convenient and instant warning function for the material level monitoring of the on-site personnel;

⑤Wide AC and DC power input can not only effectively reduce inventory, but also have a wider range of applications;

⑥It is suitable for level monitoring of liquid, granular and thick substances.

vibrating fork is suitable for chemical plastics, pharmaceuticals, feed, environmental protection, water treatment, cement and chemical fertilizers, food powder and other manufacturing and processing industries.

The piezoelectric crystal element is used to generate vibration waves. When the measured medium contacts the fork body, the amplitude and amplitude of the vibrating fork are changed. The intelligent control circuit detects this change and converts it into the corresponding output switch signal, such as: Relay, NPN , PNP.
