Introduction
The Endress+Hauser Liquipoint FTW23 is a compact, cost-effective capacitive point level switch designed for hygienic and industrial applications with water-based liquids. Built to meet global hygiene standards, it delivers reliable level detection in tanks, vessels, and pipes, with easy installation, CIP/SIP compatibility, and IO-Link connectivity for seamless integration and parameterization.
Key advantages
1. Hygienic, Cleanable Design: Certified for CIP/SIP cleaning up to 135°C for 1 hour, with IP69 protection and 3A/EHEDG approvals for food-grade use.
2. Wide Media Compatibility: Detects water-based liquids with dielectric constant >20 out of the box, adjustable via IO-Link for media >1.5 without calibration.
3. Compact & Versatile: Space-saving design fits tight spaces; multiple thread connections (G1, G1/2, G3/4, M24) suit diverse process installations.
4. Smart IO-Link Functionality: Simplifies configuration, reduces wiring complexity, and enables easy parameter setting via engineering tools.
5. Reliable & Durable: Withstands process temperatures up to 100°C (standard) and pressures from -1 bar to 16 bar abs, with 316L/PEEK wetted parts for longevity.
