Product Description

YH-301B tuning fork level limit switch is a compact type of level limit switch.

A tuning fork causes by internal crystal resonance, when the tuning fork is immersed by liquid or
solid, the vibration frequency changes, and detected by the electronic circuit, then output a switch
signal. Tuning fork level limit switch is immune to medium electrical parameters and turbulence,
agitation, bubbles, vibration and other factors, no moving parts, so don’t need maintenance and
adjustment. It is the ideal choice for complex condition.

 

Features
1. Automatic learning, through the press, without calibration, you learn different medium density;
2. All metal construction, durable;
3. Fork vibration amplitude, amplitude is above 10MM, can shake off the induction of local attachment
rods with low viscosity to prevent malfunction;
4. Super bright red LED lamp, material level monitoring on site personnel to provide more convenient
and immediate warning;
5. Wide range of AC and DC power input, not only can effectively reduce inventory, and more widespread
application;
6. Suitable for liquid and granular, dense material level monitoring.

 

Application

Tap water, mineral water, gasoline and diesel

Liquids that can produce gas

Pulp, glue, dyes, chemicals

Beer, beer fermentation agent, beverage waste water, mud, acid and alkali solution

Waste water, mud, acid and alkali solution

 

Working Principle

Vibration-wave generation using piezoelectric crystal element, when measured media contact at the forks, which change the amplitude of the tuning fork and the amplitude, by intelligent control circuit detects the change, and are transformed into the corresponding output switches signal, such as Relay or NPN or PNP.
