Model with thread proccess connection.

The side mounting level switches are used to control the level in tanks and containers in which non-scaling or residual waters, oil, chemical products, etc. are used.

The models are certificated for use in potentially explosive Dust or Gas atmospheres hazardous areas.

When the level of the liquid reaches the level of the float switch, the float changes its position an angle and activates a micro switch or a REED switch in high temperature models due to this deviation.

When the liquid level falls, the float moves back and the switch is disengaged.

The thread is G 1 " 1/2 tappered and the device can be fixed using 1 or 2 nuts or screwing the float in a pipe.

For a correct use of the level switch, the float must not touch the walls of the tank and it is necessary to ensure the free movement of the float.

For use in potentially explosive Dust or Gas atmospheres hazardous areas the installation must be done according to the Standard and Normative documents.
