The Soliphant FTM21 point level switch is suitable for level detection of non-flowing fine and coarse bulk solids. Its versatile design is widely applicable. It can be used in dust and explosion hazardous areas.
Benefits
No calibration required: simple commissioning (plug and play)
Buildup-resistant and maintenance-free
No mechanical moving parts, no maintenance, no wear and a long service life.
Sensor made of 316L: virtually no damage even when rubbing against building materials
F16 plastic housing with a window in the cover to view the switching status from outside; F18 aluminum housing available
Unaffected by external vibration and flow noise
ATEX II 1/3 D explosion protection with FM or CSA certification
Application areas
The Soliphant T is a rugged vibronic point level switch for fine and coarse bulk solids in silos. Its versatile design demonstrates wide applicability, and it is approved for hazardous areas with dust and flammable substances. The FTM20's one-piece vibrating rod design (250 mm) can be installed in any orientation. Typical applications include grain, coffee beans, sugar, animal feed, rice, detergents, dye powder, chalk, gypsum, cement, sand, plastic granules, etc.
