Point level transmitter
Capacitance Point level switch for liquids
The Liquicap M FTI5x is used for point level detection.
It is preferably used for the following measuring tasks:
• Detection of liquids and pastes that are highly viscous and tend to form buildup
• Interface detection of different liquids (e.g. oil on water)
• Two-point control (e.g. pump control) with just one process connection
• Foam detection of conductive liquids
Thanks to its robust and tried-and-tested construction, the probe can be used both in vacuums and in overpressure up to 100 bar. The materials used allow operating temperatures from –80 °C to +200 °C.
• Active buildup compensation for high-viscosity media
• Easy and fast commissioning at the press of a button
• Universal application thanks to wide range of certificates and approvals
• Corrosion-resistant, FDA-listed materials in contact with the process
• Two-stage overvoltage protection against discharge from the container
• Short reaction times
• No need for recalibration after replacing electronics
• Use in safety systems with specific requirements in terms of functional safety to SIL2/SIL3
• Automatic monitoring of electronics
