Strong Adaptability Tuning Fork Level Switch Maintenance Free
Working Principle of Tuning Fork Level Switch
NYYCUK tuning fork level switch is a universal level limit switch.
The tuning fork is excited by a piezoelectric crystal to vibrate.
When the tuning fork is immersed in a liquid or solid, the
vibration frequency changes. This frequency change is detected by
an electronic circuit. Tuning fork level limit switch is not
affected by dielectric constant, turbulence, agitation, bubbles,
vibration and other factors, no moving parts, so no maintenance and
adjustment, is the ideal choice for level switch under complex
working conditions, the application of the latest intelligent chip
can be used as oil-water interface switch.
Design feature of Tuning Fork Level Switch
◎ suitable for measuring medium density solid powder or particles
that can flow freely. It is also applicable to almost all liquid
media. This series of tuning fork level switches can measure a
variety of levels, with functions such as high / low fault safety
limit switches, overflow or idling protection, pump control, and
display of whether there is flow in the pipeline.
◎ strong adaptability - different electrical parameters and
densities of the tested materials do not affect the measurement.
Incrustation, agitation, turbulence, bubbles, vibration, medium
viscosity, high temperature, high pressure and other adverse
conditions also have no impact on the 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.
◎ 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. A variety of models
can be suitable for different applications.
◎ long service life, stable performance, Safe and reliable,
