Vibration type level switch (VEGAVIB 61)
Measurement principle:
Used for measuring granular solid media. Piezoelectric drive is the core of VEGAVIB, and the vibrating element (vibrating rod) vibrates at a certain mechanical resonance frequency under the drive of piezoelectric ceramics. When in contact with the medium, the vibration frequency of the vibrating rod 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. Pressure and temperature will not affect the accuracy of the switch. The density of solid particles should be greater than 20g/L. Using contact measurement control, the surface of the vibrating rod is smooth, without corners or edges, avoiding the adhesion of granular solids and making it very easy to clean.
■ 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 1600kPa.
-Installation and maintenance are both very simple.
■ Application:
Limit detection of solid media is commonly used in overflow or idle protection systems.
Main performance parameters:
-SIL2 certification;
-Easy installation and startup, no need for specialized debugging;
-Piezoelectric driven ceramics with fixed threads;
-Very high reliability;
-The switch point is not affected by the medium;
-Wear resistant and maintenance free;
-Belonging to Plics ® Product series.
