For stand-alone systems, or as a complement to a PC or a control system,
you can monitor level data using one or two analog outputs depending on the
particular hardware configuration.
As an option, your Rosemount 5600 Radar Level Transmitter can be
equipped with an easy-to-use Rosemount 2210 Display Panel. It offers
basically the same functionality as the Radar Master package. Four sturdy
softkeys give you access to configuration routines, service functions, and
level monitoring.
Measurement Principle
The level of the product in the tank is measured by radar signals transmitted
from the antenna at the tank top. After the radar signal is reflected by the
product surface the echo is picked up by the antenna. As the signal is varying
in frequency the echo has a slightly different frequency compared to the signal
transmitted at that moment. The difference in frequency is proportional to the
distance to the product surface, and can be accurately calculated. This
method is called FMCW (Frequency Modulated Continuous Wave) and is
used in all high performance radar transmitters.
