Product Details

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 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.
