KVS100 Series Vibrating Fork Liquid / Solid Level Switch
Introduction
KVS100 series tuning fork level switch is a new type of level switch. It is
designed and manufactured using the principle of tuning fork
vibration. It is the base of the induction rod of the tuning fork
level switch. The tuning fork is driven by the piezoelectric wafer,
and the vibration signal is received by another piezoelectric
wafer, so that the vibration signal can be circulated and the
induction rod resonates. When the material contacts the sensor bar,
the vibration signal gradually becomes smaller, and the control
circuit outputs an electrical acceptance signal until the resonance
stops.
Due to the natural principle that the sensitivity of the sensing rod gradually decreases from the front end to the rear seat, no error signal will be generated when the material in the tank and the barrel are stacked upwards, touching the base of the sensing rod (rear) or discharging.
The tuning fork generates mechanical vibrations under the excitation of a piezoelectric crystal, and the vibration has a certain frequency and amplitude. When the tuning fork is submerged by liquid or solid, the vibration frequency and amplitude of the tuning fork will change. This frequency change is detected by the electronic circuit and outputs a switching signal.
Principle
The KVS100 series tuning fork level switch vibrates to tuning fork
by piezoelectric crystal and inherent frequency of tuning fork. It
can monitor continuously to the change of frequen When the tuning
fork switch is used for low alarm (or low position control), the
medium in the vessel is discharged downward passing through the
tuning fork. When it is lower than the specific location and change
the inherent frequency, this change is detected by electronic
component, the output state is shifted; when it is used for high
alarm (or high position control), the medium in the vessel go
upward and contact with tuning fork which can shift the output
state.
Features
- Customized length can reach 3m
- DPDP SPDT Relay / NPN / PNP output
- 20~250VAC / VDC, 50/60Hz
- Whole metal construction, sturdy and durable.
- Self-study function. It can study different medium density by using buttons.
- The vibration amplitude of the fork is large, and the amplitude can reach more than 10mm, which can shake off the low-viscosity local hanging material on the induction rod to prevent malfunction.
- Bright red LED warning light.
- For liquid, powder, granule, thick medium measurement.
