Non-measurement zone below the process connection.
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.
Direct Plus mode is an alternative measurement mode. If it is possible
there will be an interference signal in the measurement zone that is larger
than the level signal, select "Direct Plus" mode. If you select "Direct Plus"
mode, the device locks on the level signal and monitors changes in level. If
the device then finds larger reflections in the silo, it will only monitor the
largest signal in a small search zone around the first reflection found and
ignore all other reflections. The interference signal must not be near to the
level signal.
The distance from the face of flange to the level (1 product) or the surface
of the top product (2 or more products). See the diagrams at the end of this
section.
A new generation of antenna made of PP or PTFE. It has an ellipsoidal
shape for a more precise emission of radar signals.
Device Type Manager. A driver for use in the PACTware™ program. All data
and functions of the device are included in it.
generate electromagnetic fields during operation. Refer to European
standard EN 61326-1 for further details.
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).
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.
A common antenna for most applications. It is used for the controlled
emission and collection of radar signals.
False radar reflections.
