Vibronic point level detection- Soliphant FTM50
Universal point level switch for fine-grained bulk solids also for explosion-hazardous areas
Soliphant M is a robust point level switch for use in silos containing fine-grained or powdery solids
even with a low bulk density. Suitable for a wide range of applications with international certificates
for use in dust or gas incendive hazardous areas. Available with polished fork and stainless steel
housing with Tri-Clamp or with aluminum housing and coated fork. Maintenance-free device for use
in typical applications like: cereals, flour, cocoa, sugar, animal feed, dye powder, chalk
Benefits
-
SIL2 in accordance with IEC 61508
-
No mechanically moving parts: no wear, long operating life
-
Insensitive to external vibrations and build-up: maintenance-free operation, independent of bulk solids
-
Various electronic inserts: e.g. NAMUR, relay, thyristor and PFM-signal outputs for optimum alignment with the plant control system
