    Product description

    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 8112 is available with different sensor lengths using a 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 (not suitable for measuring the foam thickness itself), buildup or varying products.
