E+H Soliphant FTM21 Vibronic Point Level Switch

Soliphant FTM21 is a point level switch for applications with fine-grained or coarse-grained, non-fluidized bulk solids. The various designs means the device has a wide range of applications. Certificates are also available for use in dust and hazardous areas.

  • No calibration required, easy commissioning (plug and play)
  • Measurement not affected by build-up or external vibration
  • No mechanically moved parts, free of maintenance
  • Sensor material 316L, abrasion resistant even with building materials
  • Plastic housing with cover with sight glass, switch status visible from outside; also aluminium housing available
  • Not affected by flow noises
  • Available with explosion protection certificates
