1. With automatic learning function, you can learn different media densities without calibration by pressing keys;
2. All metal structure, solid and durable;
3. The fork body has a large vibration amplitude of more than 10mm, which can shake off the low viscosity local hanging materials on the sensing rod to prevent misoperation;
4. Super bright red LED light provides more convenient and immediate warning function for material level monitoring of on-site personnel;
5. Wide AC and DC power input can not only effectively reduce the inventory, but also be used more widely;
6. It is applicable to material level monitoring of liquid, granular and thick substances.
The tuning fork (liquid) level switch is designed based on the damping effect of medium on tuning fork vibration and the principle of piezoelectric effect. The sensing part of the detection material (liquid) level is composed of tuning fork, which has a fixed vibration frequency and amplitude vibration. When the tuning fork is damped by the medium, the tuning fork stops vibrating, and the control circuit drives the relay to send a switch signal. This product can adapt to severe working conditions and is reliable. It is the most widely used product in material (liquid) level switch instruments.
Piezoelectric crystal elements are used to generate vibration waves. When the measured medium contacts the fork, it changes the amplitude and amplitude of the tuning fork. The intelligent control circuit detects this change and converts it into corresponding output switch signals, such as Relay, NPN, PNP.
