* Be mindful of oil viscosity
SKF float switches may only be used in mineral and synthetic oils up to a maximum effective viscosity of 1 500 mm²/s. Use in media with an effective viscosity > 1 500 mm²/s can cause an increase in the shear forces between the float and contact tube, leading to failure of the float switch. This can result in insufficient lubrication and thereby to machine damage.

Fill level switches WS32-x / WS33-x / WS35-x

Fill level switches monitor the fill level in non-pressurized fluid reservoirs. To meet different requirement, fill level switches either have one or two switching points. 

If fill level switches have one switching point (WS32), the minimum fill level in the reservoir is monitored. Fill level switches with two switching points either monitor the minimum and maximum fill levels in the reservoir so the filling stops automatically when the maximum level is reached (WS33). Or they monitor the minimum fill level and have an early warning function (WS35). 

The latter version gives a signal before a critical oil level in the reservoir is reached so oil can be topped off before the machine stops working. Other fill level switches are available on request, e g with three switching points.
