working principle:
The tuning fork type/level switch uses a piezoelectric component to generate a vibration wave. When the measured medium contacts the fork body, the frequency of the amplitude of the tuning fork is changed, and the change is detected by the intelligent control circuit and converted into a corresponding output signal.
Features:
The tuning fork type/level switch has a wide range of uses and can be used to detect materials of different densities/forms. The characteristics are as follows: DPDT, SPDT, Relay/NPN/PNP output.
All metal construction, sturdy and durable.
Wide power input 20-250VAC/VDC, 50/60HZ.
With automatic learning function, you can learn different media density by pressing and without calibration.
The vibration amplitude of the fork body is large, the amplitude can reach more than 10mm, the low-viscosity local hanging material on the induction rod can be shaken off, and the ultra-bright red LED lamp provides more convenient and immediate warning for the spot level monitoring of the on-site personnel.
It can be used for the detection of liquid, powder, granular and thick materials.
