The Liquipoint FTW33 is developed for the food industry and meets all international hygiene requirements. The device also fits perfectly for applications in all industries. For use in pasty and sticky media and media with heavy build-up.

For use in pipes and in storage, mixing and process vessels with or without an agitator. For liquids with electrical conductivity >1 μS/cm or dielectric constant >2. Developed for the food industry. Detection of foam occurring within the food industry possible.

• Process connections: Threads and hygiene connections

• Sensor length: Flush-mounted

• Temperature: -20 to +100°C (-4 to +212°F), CIP/SIP to 150°C (302°F) for 1 hour

• Pressure: 0 to 25bar abs (0 to 362,5psi abs)

• Hygienic certificates

• Perfect fit to the hygienic industry thanks to flush-mounted design, which allows pigging of pipes

• Safe and reliable measurement due to build-up compensation, ensuring reliable switching; IO-Link reduces costs and complexity due to easy configuration and flexible integration in all fieldbus systems

• Individual adjustment to each medium not necessary

• Easy installation thanks to compact design, even in tight conditions or where access is restricted

• Broad range of process connections for installation in new and existing plants

• CIP and SIP cleanability ensured - up to protection class IP 69

• LED display for on-site function check
