Compact Level Detection for Water-Based Liquids
The Liquipoint FTW23 is a capacitive point level switch designed for detecting the presence or absence of water-based liquids.
Its compact design makes it practical for storage tanks, mixing vessels and pipes, especially where installation space is limited or access around the process connection is restricted.
Rather than requiring a large measuring system, the FTW23 provides a straightforward solution for applications that only need reliable point level detection.
A Simple Solution That Does Not Require Individual Medium Adjustment
One of the practical advantages of the FTW23 is that individual adjustment to each medium is not necessary for its intended applications.
For factory settings, the device is designed for media with a dielectric constant above 20. With IO-Link adjustment, media with a dielectric constant above 1.5 can be detected, according to the selected application and configuration.
This makes commissioning simpler when different water-based liquids are handled within the applicable range.
IO-Link Makes Configuration Easier
The FTW23 supports IO-Link, allowing device parameters to be configured through engineering tools.
For plants using IO-Link infrastructure, this can reduce the complexity of device setup and make parameter management more convenient compared with purely manual configuration.
The device also provides an LED display for an immediate on-site function check.
Built for Hygienic Processes
The FTW23 was developed for the food industry and meets international hygiene requirements. It is available with 3-A and EHEDG hygienic approvals, making it suitable for hygienic process installations where cleanability and material compatibility are important.
The sensor is made from 316L, with PEEK used as the sensor insulation.
Ready for CIP and SIP Cleaning
For hygienic production environments, cleaning conditions are often just as important as normal process operation.
The FTW23 is designed for CIP and SIP cleaning and provides protection up to IP69. Its standard process temperature range is -20 to +100°C, while cleaning temperatures can reach 135°C for up to one hour.
This gives the device the flexibility required for regular cleaning cycles in suitable food and beverage installations.
Designed for Tight Installation Spaces
The compact construction is one of the reasons the FTW23 fits well into smaller process systems.
It can be installed where access is restricted, while process connections are available with G1, G1/2, G3/4 and M24 threads, depending on the selected configuration.
Reliable Point Level Detection Without Overcomplicating the System
The FTW23 is not intended to replace a continuous level transmitter when a complete level profile is required. Its strength is simpler: detecting a defined liquid level reliably and economically.
For water-based liquids in tanks, pipes and mixing vessels, this compact approach can provide exactly the level information the control system needs without adding unnecessary complexity.
