Simple mechanical mechanism, extremely robust and cost-effective point level switch for bulk solids
Field of application
The economical Soliswitch FTE20 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 polymers make the unit outstandingly robust and therefore suitable for use in dust explosive areas according the latest standards.
