Point level switch
Soliswitch FTE31
Rotary paddle switch

Simple mechanical mechanism, extremely robust and cost-effective point level switch for bulk solids

The economical Soliswitch FTE31 is a paddle switch for point level detection in bulk materials. Its robust polymer housing and compact design makes it an ideal sensor for full, empty and demand alarm in applications with bulk solids. The optimized materials make the unit outstandingly robust and therefore suitable for use in dust explosive areas.
