Endress+Hauser Soliswitch FTE20 Rotary paddle switch

The economical Soliswitch Endress+Hauser FTE20 is a paddle switch for point level detection in bulk materials. Its robust polymer housing and compact design make it an ideal sensor for full, empty, and demand alarm in applications with bulk solids. According to the latest standards, the optimized polymers make the unit outstandingly robust and, therefore, suitable for use in dust explosive areas.

  • Safety comes first – Overfill prevention with an automatic rotation monitoring system
  • Optical rotation control for a fast and easy check either for installation or for trouble shooting
  • Extremely robust polymer housing with the latest dust Ex certification for ATEX, FM and CSA
  • Cost savings over the whole life cycle:
    Fast order process due to E-direct
    Quick installation
    Fast trouble shooting concept without the need of demounting
    Best price performance ratio in the market
  • Adjustment to weight of solids without the need for tools
  • Housing can be rotated 360° to enable optimal alignment following installation.
  • Process connections: NPT 1½”, PBT; NPT 1¼”, PBT; G 1½”, PBT; NPT 1½”, 1.4305; NPT 1¼”, 1.4305; G 1½”, 1.4305′
