Hastelloy C material tuning fork level switch Operating Principle

NYYCUK tuning fork level switch is a new type of level switch. It is designed and manufactured by using the principle of tuning fork vibration. It is an induction rod base on which the tuning fork is opened and closed, which drives the tuning fork through the piezoelectric chip and receives the vibration signal by another piezoelectric chip, which circulates the vibration signal and resonates with the induction rod. When the material is in contact with the induction rod, the vibration signal becomes smaller, and the control circuit outputs the electrical connection signal until the resonance is stopped. Because of the natural principle that the sensibility of the inductive rod decreases from the front end to the back seat, when the material in the tank accumulates up with the barrel, it touches the bottom of the inductive rod There is no error signal when the seat is in the rear or when discharging. In short, the tuning fork produces mechanical vibration under the excitation of piezoelectric crystal, which has a certain frequency and amplitude. When the tuning fork is immersed in liquid or solid, the vibration frequency and amplitude of the tuning fork will change. This frequency change is detected by the electronic-subcircuit and outputs a switch quantity.

Design Features

The fork body and flange part of the tuning fork level switch adopts Hastelloy alloy, which is more widely applied in the field and occasion. Hartz ultra low carbon alloy type, Ni, Mo, Cr series nickel-based hartz alloy, corrosion resistant, high temperature resistant material (Hastelloy), because it has excellent high temperature resistance, oxidation resistance, corrosion resistance weld influence area, has good long-term heat stability and machinability, in agricultural chemical, nuclear, biological, pharmaceutical and other harsh industrial environments are used. It in wet oxygen, sulfurous acid, acetic acid, formic acid and the strong oxidizing salt medium, also have excellent corrosion resistance, uniform corrosion, intergranular corrosion resistance, therefore also widely used in chemical industry, the conductivity of the alloy hartz gold and coefficient of thermal conductivity than mild steel is much lower, and the resistance rate and inflation rate are much higher than low carbon steel, the molten pool of liquidity is poor, poor wettability, penetration is small, Melting depth.
