Product Details
KVS100 Series Vibrating Fork Liquid / Solid Level Switch
Introduction
KVS100 series is a compact vibrating fork liquid level switch. It
can be applied to the level measurement of vessels and storage
tanks under difficult conditions. It is not only suitable to use in
foams, air bubbles, viscous liquid and conditions with complex
vibrating interference, but also particularly suitable to be
installed in small containers and tanks with constricted mounting
space. The design principles are also based on detecting the change
of the vibration frequency when fork body is immersed in medium.
Principle
The KVS100 series vibration 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 isdetected
by the intelligent control circuit and converted into a
corresponding output signal. Such as: (Realy.NPN.PNP)
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.
