Add to Cart

Float switches are switching devices operated by a float moved by fluid. They are used to control the tank fluid levels in small power units type ABSKG ... NG10; 20; 40 and 60.

The sliding tubes contain two fixedly set reed contacts (normally closed contact and normally open contact) that are switched by the permanent magnets installed in the float.

Fixedly set temperature contacts (option) are fitted to monitor the max. hydraulic fluid temperature.

Function of level switch

When the float reaches the switching points while the oil level is falling, the contacts are operated magnetically. The switching positions of the contacts are maintained until the float passes the switching points again due to a rising oil level.

Switching point L1 is a normally closed contact, the contact function of switching point L2 is optionally a normally closed or normally open contact.

 

Level switch function

When the float reaches the switching points while the oil level is falling, the contacts are operated magnetically. The switching positions of the contacts are maintained until the float passes the switching points again due to a rising oil level.

Switching point L1 is a normally closed contact, the contact function of switching point L2 is optionally a normally closed or normally open contact.

 

Temperature contact function

A bimetal plate, which is influenced by temperature, switches when a firmly set response temperature is reached. The temperature contact is not suitable for temperature controlling, but merely for a shutdown function.

Installation information

Vertical installation according to technical data (see “Technical data”) Avoid flows Do not expose the switch to heavy impacts and bends Avoid external magnetic fields. Thus, the function of the reed contacts may be impaired.

 

Electrical connections:

Electrical connections may only be established by specialists Tighten the round connectors M12 x 1 and/or mating connectors after connection Only plug in the round connectors M12 x 1 and/or mating connectors in the de-energized condition Do not overload the contacts (see “Technical data”) In case of inductive load provide a protection circuit!
