The Spirax Sarco LC2650 is a level controller for conductive liquids.","It provides on\/off or modulating control of liquid levels in boilers, tanks, and vessels operating up to 32 bar at 239 ° C.","It has two alarm channels that can be independently configured either high or low.","The controller is suitable for use with liquids having an electrical conductivity as low as 5 μS\/cm or 5 ppm (when used with an LP20, PA20 or PA420 capacitance probe).","The front panel has an LCD screen and a five-button keypad. The LCD display screen can show either operating information (in run mode), or a trend graph that displays a record of the variation in level over a set time.","In run mode the general data is shown on several consecutive screen displays.","A test function provides the operator with a diagnostic feature. Inputs can be measured and outputs can be set from the front panel.","To prevent unwanted or inadvertent changes being made, all commissioning parameters are protected with a pass code. The LC2650 can communicate via an infrared link between adjacent controllers.","It can be designated as either a master unit or a slave unit.","The LC2650 can be panel, DIN rail or chassis mounted.","Principal features:
