Span limits
Maximum span = URL (can be further adjusted
up to ± URL
(TD = 0.5) for differential models, within
the range limits)
IT IS RECOMMENDED TO SELECT THE TRANSMITTER
SENSOR
CODE PROVIDING THE TURNDOWN VALUE AS LOWEST
AS
POSSIBLE TO OPTIMIZE PERFORMANCE
CHARACTERISTICS.
Zero suppression and elevation
Zero and span can be adjusted to any value
within the range
limits detailed in the table as long
as:
— calibrated span ≥ minimum span
Recommendation for square root
function
At least 10% of Upper Range Limit

Damping (feature not available for
WirelessHART version)
Selectable time constant : between 0 and 60
s
This is in addition to sensor response
time.
Turn on time
Operation within specification in less than
10 s with minimum
damping.
Insulation resistance
