Parameters
Fixed reference density Enter the fixed value for the
reference density.
Linear expansion coefficient Enter the linear, fluid-
specific expansion coefficient
for calculating the reference
density.
Square expansion coefficient For media with a non-linear
expansion pattern, use this
function to enter a quadratic,
fluid-specific expansion
coefficient for calculating the
reference density.
Temperature unit Select the unit for
temperature.
Result
The selected unit applies for:
– Current outputs
– Reference temperature
– Simulation process
variable
Reference temperature Enter the reference
temperature for calculating
the reference density.
Current span Select the current range for
the process value output and
for the upper and lower level
for signal on alarm.
4 mA value Enter the value for the 4 mA
current.
20 mA value Enter the value for the 20 mA
current.
Failure mode Select the value the current
output adopts in an alarm
condition.
Failure current Select the current value the
current output adopts in an
alarm condition.
