The KROHNE OPTISWITCH 5150 C is a vibrating level switch for use with hygienic applications for all liquids. Utilizing tuning fork technology, the 5150 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 5150 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 5150 C is a compact instrument that is suitable for mounting in cramped spaces including most vessels, tanks and pipelines. The 5150 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.

The KROHNE OPTISWITCH 5150 C is available with a number of options to tailor the unit to a variety of applications. A number of hygienic process connections are available. Each process connection is made of polished stainless steel with surface roughness (Ra) less than 0.8 µm. A high temperature option allows use in environments up to 250 °C (the standard temperature limit is 150 °C). The unit also functions in pressures up to 64 bar. Standard accuracy is approximately 2 mm (0.08") with vertical installations.
