The KROHNE OPTISWITCH 4000 C is an economical vibrating level switch for use with all liquids. Utilizing tuning fork technology, the 4000 C is designed for industrial use in all areas of process technology. Typical applications are overfill and dry run protection. Thanks to its simple and robust measuring system, the OPTISWITCH 4000 C is virtually unaffected by the chemical and physical properties of the liquid. It functions even under difficult conditions such as turbulence, air bubbles, foam generation, buildup, strong external vibration or changing products.
The OPTISWITCH 4000 C is a compact instrument. With a tuning fork only 40 mm length, the unit can be mounted in cramped spaces including most vessels, tanks and pipelines from DN 25. The 4000 C can also be operated without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, a connected device can be directly activated.
