LCF level controller combines a 2 point float type level probe (LCSFC) and a standard LC05 controller installed inside an ABS protection enclosure with IP66. A large variety of versions based on different plastic and stainless steel floats are available. Floats with different dimensions and specific gravity are available for liquid density down to 0.45 g/cm3, temperature up to 135°C, and pressures up to 50 bar.Various process connections as well as an option for vertical adjustment are available. LCF can be used for liquid filling or emptying control by switching on and off vessel supply or drainage devices such as pumps and magnet valves. The controller allows the operator to select relevant output relay action for either supply or drainage control. Thanks to the compact combination of probe and in-head controller, LCF can be very useful for building cost-saving level control applications.
