Capacitive Level Measurement

Application
The Liquicap M compact transmitter is used for the
continuous level measurement of liquids. Thanks to its robust and tried-and-tested construction (self-sealing cone), the probe can be used both in vacuums and in overpressure up to 100 bar. The sealing and insulation materials used allow operating temperatures of –80 °C to +200 °C in the medium container. The measurement is independent of the dielectric constant (DK) as of a liquid conductivity of 100 μS/cm. In this way, various liquids can be measured without the need for recalibration.
Used in conjunction with Fieldgate (remote measured value interrogation using Internet technology), Liquicap M provides an ideal solution for inventorying materials and optimizing logistics (inventory control).

Your Benefits
• No calibration necessary for media with a conductivity
of 100 μS/cm and higher. The probes are calibrated to the ordered probe length on leaving the factory (0 % to 100 %). This makes easy and fast commissioning possible.
• Menu-guided local configuration via plain text display
(optional)
• Universal application thanks to wide range of certificates and approvals
• Use also in safety systems requiring functional safety to
SIL2 in accordance with IEC 61508
• Material in contact with the process made of corrosion-resistant material and FDA-listed materials for wetted parts
• Two-stage overvoltage protection against discharge
from the container (gas discharger + protective diodes)
• Electronics can be switched for media forming buildup
• Short measured value reaction time
• No need for recalibration after replacing electronics
• Automatic monitoring of electronics
• Monitors damage to insulation and rod breaking or rope tearing
• Suitable for interface measurement
