2.2 Device description
This device is a 24 GHz FMCW-radar level transmitter. It is a non-contact technology and is 2-
wire loop-powered. It is designed to measure the distance, level, mass, volume and reflectivity of
liquids, pastes and slurries.
Radar level transmitters use an antenna to guide a signal to the surface of the measured
product. The device has many antennas available. Thus, it can measure most products even in
difficult conditions. Also refer to
Technical data on page 100.
The device has a set-up wizard, fully-potted electronic circuit boards and online help functions.
You usually will not need this Handbook to install, set up and operate the device.
If it is ordered with the applicable options, it can be certified for use in hazardous areas.
These output options are available:
•1 output: 4...20 mA (HART)
•2 outputs: 4...20 mA (HART) + 4...20 mA
•4-wire FOUNDATION™Fieldbus output (with a local HART®connection for device
configuration)
•4-wire PROFIBUS PA output (with a local HART®connection for device configuration)
These accessories are available:
•Stainless steel weather protection.
•RS232 / HART®converter (VIATOR).
•USB / HART®converter.
