Level Switches

Magnetic float level switches can provide level measurement for almost all liquid media. Properly used, float switches can deliver millions of on/off cycles, for years of dependable operation. They are ideal for narrow level differential applications such as high or low level alarms and controls in power plants. Youll find them anywhere there is pump and level control, i.e., wherever liquid flows in and out of tanks, pressure vessels, or sumps: Chemical industry Petrochemical industry Natural gas Offshore Shipbuilding Machine building Power generating equipment Power stations Process water and drinking water treatment Locomotive & railroad equipment Off highway vehicles Bulk storage terminals Textile, pulp & paper industries Food, beverage, & dairy industries

Capacitance is measured between 2 probes that are electrically isolated from one another by a nonconductor (dielectric). Type of Probes : A) Flexible Rope: A flexible PTFE insulated SS rope for measurement of liquid in the tank. In this case the tank is considered as the second probe. B) Rigid Rod : A Rigid PTFE insulated SS rod for measurement of liquid in the tank. In case a concentric pipe is provided then the pipe acts as the second electrode . If concentric pipe is absent then the tank is considered as the second electrode. C) Non Insulated Rigid Rod : A Rigid non insulated SS rod for measurement of liquid in the tank. A concentric pipe is provided which is isolated from the centre rod.This is used for non conducting liquids
