ELESA original design
EN 848 float switches can be used to monitor the fluid level by actuating an electrical switching contact as soon as a defined fluid level is exceeded or falls below a defined mark.
The desired level at which the switching point is to be reached is determined by the length of the float stick. With the float removed, this stick can be shortened; a scale for fluid or water facilitates determining the exact length.
The top end of the float stick features a magnet which activates a REED contact when the appropriate position is reached, regardless of the medium to be monitored.
Depending on the installation position of the magnet in the float stick, either the normally open contact (NO) or the normally closed contact (NC) may be utilized. Float switches come with the magnet set in the normally open contact position (NO).

To change the contact type (NO or NC), loosen the knurled screw on the housing and pull out the float stick. The switching magnet can now be placed into the recess on the opposite side, with the effect that the contact type changes. Each housing is provided with a label that explains this mode of function. |
