Level switch for extreme process conditions.

With the new OPTISWITCH 5300 C, Krohne presents a vibration level switch for liquids that can withstand extreme process conditions such as hot or cryogenic temperatures and high process pressure. The application area ranges from chemical or oil & gas related industries, marine (LNG) tankers to steam generation.

OPTISWITCH 5300 C provides overfill prevention, high/low level alarm, or dry run protection for pumps in liquid applications with a temperature range from -196…+450°C / -321…+842°F and pressure range from -1…160 barg / -14…2,320 psig. Insertion lengths are available up to 3 m / 9.8 ft with a wide variety of sensor materials and process connections. The wetted parts of OPTISWITCH 5300 C are made of Inconel Alloy 718 with 316L or Hastelloy C-22. Communication options include 2-wire 8/16 mA output, relay (DPDT) and transistor PNP/NPN electronics.

The new level switch features Ex, WHG (German Wasserhaushaltsgesetz), various ship approvals and fulfills the requirements for use in boilers and auxiliary installations according to EN 12952-11 (water tube boilers) and EN 12953-9 (shell boilers). OPTISWITCH 5300 C is designed for use in safety loops: as a single device for a single safety function (1oo1), it meets SIL2 architecture, in a homogenous redundant setup, it meets SIL 3 (1oo2) architecture.

The new switch adds to the KROHNE range of vibration level switches that provide accurate and reliable point level detection: the OPTISWITCH 4000 and OPTISWITCH 5000 series are designed for liquid applications, while the OPTISWITCH 3000 series is designed for use with solids.
