Application area : Liquids [density: > 0.5 … 2.5 g/cm³ (0.018 … 0.09 lbs/in³)] : The VEGASWING 51 is a universal level switch with small dimensions for use in liquids. Independent of the mounting position, it detects reliably with millimetre accuracy the limit level. The instrument can be used as empty or full detector, as approved overfill protection, dry run protection or pump protection in vessels and pipelines. The VEGASWING 51 is an economical solution with maximum reliability and safety.
Function : The heart of the sensor is the vibration drive by which the tuning fork is energized to vibrate at its resonance frequency. When covered with medium, the frequency of the fork decreases. This frequency change is processed by the integrated electronics and converted into a switching command. With the tuning fork with only 38 mm length, the VEGASWING work reliably independent of the installation position in any liquid. Pressure, temperature, foam, viscosity and the composition of the liquid do not influence the switching accuracy.
Materials : The wetted parts of the instrument are made of stainless steel 316L. The supplied process seal is made of Klingersil C-4400
Housing versions :
Operation : No adjustments on the instrument are necessary. The switching function is determined by the electrical connection.
