New vibration level switch for liquid applications
For hot or cryogenic temperatures as well as high process pressure
SIL2/3 compliant; various approvals for use in hazardous areas
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.
