LC2250
Level Controller
Description
The Spirax Sarco LC2250 is a level controller for on/off or modulating control of conductive liquid levels.
The LC2250 has two alarm outputs that can be configured high or low.
The controller is suitable for use with liquids having an electrical conductivity of 5 μS/cm or 5 ppm, when used with an LP20, PA20 or
PA420 capacitance probe.
The LC2250 may be used on boilers, tanks, or vessels operating at up to 32 bar g at 239 °C.
The front panel has a 3 digit LCD display and a five-button keypad.
The unit can be be panel, DIN rail, or chassis mounted.
