8112 Vibrating Level Switch
Brand: Burkert Fluid Control SystemsDoes not ship to OH, United States
The 8112 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 Type 8112 is available with different sensor length using tube extension. The right length can be adapted thanks to a lock fitting.
Due to the simple and rugged measuring system, the 8112 is virtually unaffected by the chemical and physical features of the liquid. It works even under unfavourable conditions such as turbulence, air bubbles, foam generation, buildup or varying products.
Features- For universal use as overfill or dry run protection system
- Setup without adjustment
- For food and beverage industry thanks to surface finishing < 0.8 µm
- ATEX approvals
