Dead zone
Non-measurement zone.
Dielectric constant
An electrical property of the product to be measured used in Radar
measurement. Also known as εr, DK and relative permittivity. Defines the
strength of the wave reflected back to the device's signal converter.

Electromagnetic compatibility Defines how much a device influences or is influenced by other devices that
generate electromagnetic fields during operation. Refer to European
standard EN 61326-1 for further details.

FMCW
Frequency-modulated continuous-wave radar technology. The signal is
continuously present, but the frequency is modulated, usually in
successive linear ramps over time (frequency sweeps).

Hazardous area
An area with a potentially explosive atmosphere. Trained personnel can
install and use a device in this area. The device must be ordered with the
appropriate options. The device requires approvals (ATEX, IECEx, FM, CSA,
NEPSI etc.) related to site specifications. You can find more data about
hazardous areas in the Ex Manuals and Ex Certificates of Compliance.

Horn (cone) antenna
A common antenna for most applications. It is used for the controlled
emission and collection of radar signals.

Interference signals
False radar reflections.
Level
Height from the bottom of the tank (user-defined) to the surface of the top
product (Tank height – distance). See the diagrams at the end of this
