Application
The Soliphant T is a robust point level switch for silos containing fine or coarse-grained, non-fluidized bulk solids. 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 (see accessories).
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.
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.)
