B.1.2 Operation
Application
Operation mode
The Rosemount 2160 has three operation modes:

Standard
Enhanced (Fault=WET)
Enhanced (Fault=DRY)
Sensor output delay
When the Rosemount 2160 detects a change in process conditions from wet-to-dry or dry-
to-wet, the Sensor Output Delay parameter causes a delay of up to 3600 seconds before a
new process condition is indicated in the process variables.
If, for example, there are waves in a tank, then the Rosemount 2160 may intermittently
detect a change in process conditions. The sensor output delay ensures that the fork of the
level detector is dry or wet for a period before switching.
Depending on the application, a suitable delay can prevent constant switching of the
output state.
Media density
The vibration frequency of the fork sensor varies depending on the density of the process
liquid. For higher accuracy of switching points, to select one of the following options:

Option
Normal
Low

Sensor stabilization time
The time needed for the fork sensor to reach a stable vibration may vary depending on the
process conditions. Sensor Stabilization Time sets a delay before taking a frequency
measurement.
The default setting is 60 ms. It can be set to a time in the range 20 to 1000 ms and is
adjustable in 20 ms steps. Alternatively, the setting AUTO is for the Rosemount 2160 to
automatically calculate a delay.

Description
Default operation mode for no sensor fault detection.
Output is forced to Wet when fault detected.
Output is forced to Dry when fault detected.
Description
Select when the specific gravity of the process liquid is between
0.7 and 2.0.
Select when the specific gravity of the process liquid is less than
0.7.
Select when the specific gravity of the process liquid is greater
than 2.0.
