Displacer Type Level Switches

Thermal Instrument is the leading Displacer Type Level Switches Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

This is top mounted type level switch provided single or multiple set points. It uses displacer that do not float on the surface of liquids. Working principle of the level switch is based on a buoyancy principle. This level switch is consists of Switch Assembly, Wire Rope with Spring Assembly and Displacer suspended on spring. Displacer having more density than the process liquid is used. Spring selection is determined by the weight of the displacer. When level rises it displacer is submerged and amount of weight equal to the weight of process liquid is displaced. This displacement relives spring tension causes the actuation of micro switch. This type of level switch is used for lengths upto 10000 mm.
