Technical Information
Nivector FTI26
Capacitive
Point level switch for powdered and fine-grained
solids
Application
Reliable minimum or maximum detection of powders or fine-grained bulk solids in
silos.
• Typical application examples: plastic granules, detergent, grain, sugar, spices, milk
powder, animal feed
• Easy installation thanks to compact design - even in tight conditions or where
access is restricted.
• Also suitable for use in
– Food industry
– Hazardous atmospheres formed by combustible dust, zone 20
– Process temperatures of –20 to +80 °C (–4 to +176 °F).
Your benefits
• Onsite function check via LED indication
• Robust stainless steel housing, optionally available with M12x1 connector with
IP69 protection
• Easy and cost-effective commissioning: Precalibration in factory (plug and play)
• Hygienic design, 3-A and EHEDG certificates
• Meets the requirements of EU 1935/2004
• FDA-compliant
• DC-PNP Output and IO-Link communication
