2600T Pressure Transmitters
Model 264DR, 264PR, 264HR, 264VR, 264NR SS/264XR_2
3
(§) Double the value with the inert filling
– models 264HR/NR 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
Damping
Selectable time constant : 0, 0.25, 0.5, 1, 2, 4, 8 or 16s.
This is in addition to sensor response time
Turn on time
Operation within specification in less than 1s with minimum
damping.
Insulation resistance
> 100MΩ at 1000VDC (terminals to earth)
The combinations sensor code/seal type marked (•) modify the base accuracy rating and static pressure effect; refer to performance specifications.
Although he above table defines capillary length, for some types of seal combined to the sensor, care should be taken of the maximum working
pressure of the used seal which can limit the range.
Refer to ABB for data related to application of capillary lengths greater than those specified in above table.
