T-28E

Control of liquids
Float levels switch

Intended use

The floats are to be used to control the level in the filling and emptying processes of tanks and containers in which non-scaling clean or residual waters are used. They are specially designed to be introduced through little holes.

There is, under request, a mounting accesory made of PVC and with a G 1 “ thread that fixes the float and allows the adjustment of the level due to a cable gland.

Function

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 due to this deviation.

It is necessary to install 2 devices to control of the maximum and the minimum levels automatically.

Mechanical connection

It is simple: the switch literally hangs on its own cable at the desired height and is fixed to the ceiling or to one side of the tank adjusting the distance of the counterweight, if it was requested.

Dimensions

Approximate measures given in mm.
