4.6 Process conditions
Describe the conditions in your tank according to the Process Conditions listed below. For best
performance choose only if applicable and not more than two options.
4.7 Temperature measurement
Up to six temperature sensors can be connected to an existing 2210 Display Unit (1) .You can use 1-3 spot
elements or 1-6 multiple spot elements. All temperature sensors must be of the same type, for example,
the Pt100 or CU90.
Use one of the following temperature measurement conversion methods:

PT100

CU90

User-defined linearization table. The sensor characteristics are specified in a table of corresponding
resistance and temperature values.

User-defined formula. The sensor characteristics are specified in a mathematical formula: R=R
0
*(1+A*T+B*T 2 ) where R is the resistance at temperature T, R
0
is the resistance at zero degrees
Centigrade and A and B are constants.
Rapid level changes
Optimize the transmitter for measurement conditions where the level changes quickly
due to filling and emptying of the tank. A standard configured transmitter is able to track
level changes of up to 4 inch/s (100 mm/s). When the Rapid Level Changes check box is
marked, the transmitter can track level changes of up to 8 inch/s (200 mm/s).
Turbulent Surface
This parameter should be used if the tank shows a turbulent surface. The reason for the
turbulence might be splash loading, agitators, mixers, or boiling product. Normally the
waves in a tank are quite small and cause local rapid level changes. By setting this
parameter the performance of the transmitter will be improved when there are small and
quickly changing amplitudes and levels.
Foam
Setting this parameter optimizes the transmitter for conditions with weak and varying
surface echo amplitudes, which are typical for foam.
Solid Products
Setting this parameter optimizes the transmitter for solid products, for example concrete
or grains, which are not transparent for radar signals. For instance, this parameter can be
used when the application is a silo with product buildup.
1, The Rosemount 2210 Display Unit was discontinued Oct 2018, and is no longer available for ordering.
Sensor Mounting Level
1-6
Enter the level (from the tank bottom) at which each sensor is mounted. The first
sensor should be mounted in the lowest position in the tank, the second above the
first and so on.
Number of Sensors
Enter the number of temperature sensors connected to the Display Unit. You can
have up to six sensors connected. If you choose zero sensors temperature
measurement is disabled.
