Long Service Life Tuning Fork Level Switch Used For Liquid Dust
Working Principle of Tuning Fork Level Switch
NYYCUK tuning fork level switch is a general-purpose liquid level
limit switch. The tuning fork is excited by the piezoelectric
crystal to generate vibration. When the tuning fork is immersed in
liquid or solid, the vibration frequency changes, and the frequency
change is detected by the electronic circuit as a switch. The
tuning fork type liquid level limit switch is not affected by the
dielectric constant, turbulence, agitation, air bubbles, vibration
and other factors, and has no moving parts, so no maintenance and
adjustment are required. It is an ideal choice for liquid level
switches under complex working conditions. The smart chip can be
used as an oil-water interface switch.
Design feature of Tuning Fork Level Switch
◎ Suitable for measuring free-flowing, medium-density solid powders
or granules. Also suitable for almost all liquid media, this series
of tuning fork level switches can measure a variety of levels, with
high/low fail-safe limit switches, overflow or dry running
protection, pump control, display pipeline with/without flow, etc.
Function.
◎It is not affected by foam, eddy current and gas, and is suitable
for fixed-point alarm or control of solid material level in various
silos and liquid level in various containers. Various models are
available for different applications
◎ long service life, stable performance, Safe and reliable,
◎ Strong adaptability—different electrical parameters and densities
of the material to be tested will not affect the measurement. Harsh
conditions such as scaling, agitation, turbulence, bubbles,
vibration, medium viscosity, high temperature, and high pressure
have no effect on detection.
◎ no need adjustment: it is not affected by the dielectric constant
and density of the measured medium, so no matter what liquid is
measured, it does not need to be adjusted on site.
◎maintenance free: the detection process of the tuning fork switch
is completed by the electronic circuit. There are no moving parts.
Once it is installed and put into operation, it does not need to be
adjusted on site.
