Measurement principle:

Used for measuring liquid media. Piezoelectric drive is the core of VEGASWING, and the vibrating element (tuning fork) vibrates at a certain mechanical resonance frequency under the drive of piezoelectric ceramics. When in contact with a medium, the vibration frequency of the tuning fork will decrease. The integrated electronic component detects changes in vibration frequency and converts them into switch commands. Piezoelectric ceramics are mechanically fixed, very stable and durable. The length * of tuning fork can be as short as 40mm. Pressure, temperature, foam and bubbles, and even viscosity will not affect the switching accuracy. Due to the rated width being only DN25, there is no problem with pipeline installation.

■ Advantages:

-Almost unaffected by the characteristics of the medium.

-The medium temperature ranges from -50 ° C to 250 ° C.

-The working environment pressure ranges from -100kPa to 6400kPa.

-Installation and maintenance are both very simple.

■ Application:

Limit detection of liquid media is commonly used in overflow or idle protection systems.

Main performance parameters:
