Application

The Soliphant T is a robust point level switch for silos containing fine or coarse-grained, non-fluidised bulk solids. Soliphant T works independently from dielectric constant value and conductivity. The various designs that are available means the device has a wide range of applications. Soliphant T is available in 4 lengths and the probe length of extended versions can be easily adjusted using a sliding sleeve.  

Function

A piezoelectric drive excites the vibrating rod of Soliphant T FTM20/FTM21 to its resonance frequency. If medium covers the vibrating rod, the rods vibrating amplitude changes (the vibration is damped). Soliphants electronics compare the actual amplitude with a target value and indicates whether the vibrating rod is vibrating freely or whether it is covered by medium. The process connection is de-coupled from the rods vibration movements and thus is insensitive to vibrations and noise.

Control systems, switching units, signalling systems (e.g. lamps, horns, PCS, PLC, etc.) can be directly connected. Minimum/maximum quiescent current safety can be switched at electronic insert.

 

Application example

 

The entire measuring system consists of:

  • Soliphant T FTM20 or FTM21 with FEM22 or FEM24 electronic insert
  • A supply point and
  • The connected control systems, switching units, signalling systems (e.g. lamps, horns, PCS, PLC, etc.)
.
