FTE31 Point level switch Soliswitch FTE31 Rotary paddle switch

Field of application

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.

The universal point level switch FTE31 is used as a full, empty and demand alarm on silos containing solids. Its construction and materials make the unit suitable for use in the food industry. The unit is suitable as a level limit switch in dust-explosion-hazardous areas.

Typical applications are level detection in: Cereals, sugar, cacao, animal feeds, washing powders, chalk, dry plaster, cement, granulates, wood chips
