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.

Your benefit

  • Precise and reliable function due to product-independent switching point
  • Low maintenance costs
  • Minimum time and cost expenditure thanks to simple setup without medium

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 :

  • The instruments are available in different temperature versions and as hygienic version.
  • The housing is made of 316L and plastic PEI.
  • The different versions are available up to protection IP 67.

Electronics versions

  • The instruments are available in two different electronics versions.
  • Apart from the electronics with transistor output (PNP), a version with contactless electronic switch is also available.

Operation : No adjustments on the instrument are necessary. The switching function is determined by the electrical connection.
