NYYCUK-A Tuning Fork Level Switch With 44mm SS316L Fork and SPDT Relay Output Water Level Switch
NYYCUK-A Tuning Fork Level Switch Product Description
The tuning fork level switch is a new type of level switch. It is suitable for almost all liquid media, and it is also suitable for measuring free-flowing medium-density solid powders or particles. Since the tuning fork level switch basically has no moving parts, the mechanical wear is relatively low, so there is no need for maintenance and adjustment, and it is simple and convenient to use.
In addition, the level switch adopts foreign new technology and original imported chips, which has the advantages of long service life, stable performance, safety and reliability, and strong adaptability (different electrical parameters and densities of the measured medium will not affect the measurement), no need to adjust (no matter what kind of medium is measured, no on-site adjustment is needed) and maintenance-free, etc., it is widely used in the process control of metallurgy, building materials, chemical industry, light industry, food and other industries.
NYYCUK-A Tuning Fork Level Switch Working Principle
NYYCUK tuning fork liquid level switch is a universal liquid level limit switch. The tuning fork vibrates under the stimulation of piezoelectric crystals. When the fork is immersed in liquid or solid, the vibration frequency will change. The frequency change is detected by an electronic circuit with switching value. The tuning fork liquid level limit switch is not affected by dielectric constant, turbulence, agitation, bubble, vibration and other factors, and has no moving parts, so it does not need maintenance and adjustment. It is an ideal choice for liquid level switch under complex working conditions. The latest smart chip can be used as oil-water interface switch.
Tuning fork liquid level switch is widely used for monitoring the limit value of tap water, mineral water, gasoline, diesel, paper pulp, glue, waste water, dye, acid and alkali solution, beer, beverage and other liquid media, as well as for monitoring the limit value of solid powder, solid particles and other good flowing media.
NYYCUK-A Tuning Fork Level Switch Design Features
1. It is suitable for measuring medium density solid powder or free flowing particles. It is also suitable for almost all liquid media. This series of tuning fork level switches can measure various material levels, features high/low fail-safe limit switches, overflow or idle protection, pump controls, indicating whether to flow in the line, and much more.
2. It is not affected by foam, eddy current and gas. It 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 occasions.
3. Long service life, stable performance, safe and reliable
4. Strong adaptability - the different electrical parameters and density of the measured material will not affect the measurement effect. Such as scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature and high pressure and other harsh conditions will not affect the detection.
5. No adjustment required: unaffected by the dielectric constant and density of the medium under test, no field adjustment is required, regardless of the type of liquid under test.
6. Maintenance-free: The tuning fork switch test process is conducted by electronic circuit, no moving parts. After installation and use, no field adjustment is required.

NYYCUK-A Tuning Fork Level Switch Installation Requirements
The instrument is generally installed vertically with the fork end downward, horizontally installed or with the fork end inclined downward (when the material has strong adhesion, it is recommended to install the fork end vertically downward).
When the material is mixed with lumps or hard particles, it is recommended to adopt a vertical or inclined installation method.
Before installing on the equipment, it is recommended to use a small amount of media sample to test the calibration sensitivity. For example: immerse the meter in a window containing a medium to test the reliability of the switch.
The actual installation is generally divided into top installation (high-level monitoring of the medium), side wall installation (high or low-level monitoring of the medium), and pipeline installation (air flow monitoring of the material pump)
