The SC Series tuning fork liquid level switch does not require any calibration, is easy to install and will operate properly as a high, low or intermediate level switch with a wider range of fluids. A “sister” product line, the SC35 series vibrating fork level switch for powder and bulk solids, the SC series tuning fork liquid level switch has the same high reliability and performance.
The piezoelectric component is used to drive the tuning fork and feedback signal, which produces the
resonation on the fork. When the fork comes into contact with a material, the fork will release some frequency
signal as feedback. It will be converted into the output of the contact signal when the circuit detects the
frequency decrease of the signal.
The product relies on the damping effect by covering the testing material on the tuning fork which reduces the
vibration frequency of the tuning fork and outputs a switch signal. Therefore, there is no signal amplification
circuit inside, which can eliminate the trouble of frequent sensitivity adjustment due to the material change
