Product details

 RF admittance level switch is a general type continuous level meter which is developed from the capacitance level meter technology. The meter consists of a electronic unit, a explosion-proof shell and hard or flexible probe elements. The sensors have a variety of materials and structures. It is widely applied in the level measurement of many medium under complex condition on the basis of specific measurement principle and structure.





Key features
  • Wide versatility: measure liquid, material level; meet requirements of different temperature, pressure and medium; be applied to severe conditions, such as corrosion and impact.
  • Anti-hanging material: unique circuit design and sensor structure make measurement not be affected by sensor's hanging materials. Do not need regular cleaning. It can avoid erroneous measurement.
  • Maintenance-free: no moving parts in the process of measurement so no damage to mechanical parts so maintenance-free.
  • Anti-interference: contact measurement, high anti-interference ability. It can overcome influence of steam, foam and stir.
  • High accuracy and reliability: diversified measurement methods ensure measurement accurate and not be affected by environment. It has high stability and long life-span.
