8110 Vibrating Level Switch
Brand: Burkert Fluid Control Systems
The 8110 is a vibrating level switch for liquids, using a tuning fork for level detection. It is designed for industrial use in areas of process technology and can be used in liquids.
Typical applications are overfill or dry run protection. The small tuning fork (40 mm of length) allows the use in vessels, tanks and pipes.
Due to the simple and rugged measuring system, the 8110 is virtually unaffected by the chemical and physical features of the liquid. It works even under unfavourable conditions such as turbulences, air bubbles, foam generation, buildup or varying products.
Features- For universal use as overfill or dry run protection system
- Setup without adjustment
- Smallest mounting dimensions
