Endress+Hauser Soliphant FTM20 Vibronic Point level detection

Soliphant FTM20 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.

  • Operational safety, reliability and universal applicability through use of the tuning fork measuring principle
  • Measurement is unaffected by conductivity, build-up, turbulence, flows or air bubbles
  • Simple and fast commissioning, no calibration required
  • No mechanically moved parts, free of maintenance
  • Safe function due to self-monitoring (active frequency monitoring of the fork)
  • Easy recurring function test via test magnet
  • Suitable for constricted space due to compact design

Point level switch in compact design with stainless steel housing.
