Alfa Laval Level Switch


Application
Level SwitchThe Alfa Laval level switch is designed to fulfil the demands for precise level indication in the Sanitary and pharmaceutical production.
 
Main features are:
 
- Wetted parts in AISI 316L, stainless steel and PEEK
- Compact and hygienic design
- Process temperature -40...200C
- LED indicator integrated into the field housing
- Not influenced by foam
- Ideal for media registration through registration of changes in product dielectricity
- Quick teach option for difficult medias
- Maintenance free
 
Standard range
The Alfa Laval level transmitter is ideal for measurements in liquids such as water and beer as well as viscous, sticky fluids, such as honey, yoghurt and toothpaste. Even dry medias can be measured, eg. sugar or flour.
 
The integrated electronics provide a digital logic signal and has incorporated automatic compensation of foam, bubbles and condensate as well as sticky media.
 
Due to the high temperature limit the Alfa Laval level switch is well suitable for CIP and SIP processes.
The hygienic installation is guaranteed by using the hygienic Clamp DN 38 (ISO2852) / Clamp DN 40 (DIN32676) connection.
 
Working principle
The Alfa Laval level switch uses a high frequency signal sweep which is radiated from the sensor tip into the tank. The media will act as a virtual capacitor which, together with a coil in the sensor head, will form a circuit creating the switch point signal. This virtual capacity will depend on the di-electric value of the media which is well defined for most medias
