The Liquiphant FTL33 liquid point level switch is designed specifically for the food and beverage industry with high hygienic requirements. The Liquiphant is especially suitable for overflow protection or pump dry-run protection in storage tanks, mixing tanks and pipes.
Compact:
- The smallest vibronic sensor on the market
Safe:
- Continuous self-monitoring
- Reliable switching unaffected by the properties of the medium
Simple:
- No calibration or adjustment required
- Plug and play

Benefits:

• Designed for hygienic applications, especially in the food industry - with hygienic process connections and certifications

• Withstands CIP and SIP cleaning - highest protection rating IP69k

• Designed to meet the highest quality and environmental sustainability requirements; the self-monitoring Liquiphant provides safe switching even in the event of a power failure.

• Provides precise switch points unaffected by changes in medium properties

• Plug-and-play point level switch requiring no adjustment under changing media conditions. The measurement is unaffected by conductivity, buildup, turbulence, flow or bubbles

• No calibration, specific knowledge or tools required (e.g. software)

• Rugged stainless steel (316L) with the highest durability - no mechanical moving parts, maintenance-free
