Krohne OPTISWITCH 5300 C vibration level switch

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

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