UAD horizontal level switch type LSG

Short description
The level switch type LSA is designed for versatile applications in shipbuilding and plant engineering. The construction comprises a rugged housing with integrated flange connection in one piece without any seals or welding seams and all welded stainless steel float.

The housing cover is sealed with an O-ring and the heat shrink tubing by the cable makes it IP68 protected. The unit can be modified into an Exd version without the need to remove which simplifies procurement and installation.

Principle behind it
The principle of operation is, one permanent magnet forms part of a float assembly which rises and falls with changing liquid level. A second permanent magnet is positioned within the switch so that the adjacent poles of the two magnets repel each other.
A change of liquid level which moves the float through its permissible travel will cause the float magnet to move and repel the switch magnet to give the snap action switch operation.
