261GSUKBN21: gauge-pressure range and loop identification
ABB 261GSUKBN21 is a 261GS gauge-pressure transmitter configuration. ABB's 261GS/261AS datasheet distinguishes gauge and absolute models and lists a 3000 kPa upper-range-limit entry for the U sensor code; a configured measuring span still requires nameplate or configuration confirmation.
Technical data for identification
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | 261GSUKBN21 |
| Measurement | Gauge pressure |
| Series | ABB 2600T / 261GS |
| Sensor-code review | U code appears in designation; confirm full ordering key |
| Family range data | ABB 261GS U sensor table reaches 3000 kPa URL |
| Output | Verify installed 4–20 mA/HART configuration |
| Process materials | Confirm diaphragm and connection from order record |
For an instrument, confirm the complete ordered configuration, process limits, wetted materials or sensor interface, output protocol and installed calibration. Family values are a starting point for engineering review.
Where this configuration fits
261GSUKBN21 should be assessed in the actual equipment arrangement. Gauge-pressure measurement is referenced to ambient pressure. Confirm process minimum and maximum, overload, impulse-line arrangement, fluid compatibility and ambient conditions before choosing a pressure instrument.
A request for 261GSUKBN21 should identify the host system, process or motor duty, available supply and the expected normal and fault behavior. This makes the selection review specific to the installed equipment.
Order-code and compatibility review
For 261GSUKBN21, Decode the complete suffix with ABB's ordering table, then verify calibrated lower and upper range values, wetted materials, electrical output and approvals. A U sensor code alone does not reveal the final calibrated range or process-connection material.
Before substituting 261GSUKBN21, compare the complete label with the engineering drawing, ABB configuration data, installed accessories and site approval record. A partial designation or a similar enclosure cannot establish interchangeability.
Field checks and acceptance
Commissioning of 261GSUKBN21 should follow a controlled procedure. Isolate and depressurize the process before installation. Check the pressure connection, venting and loop wiring, then perform zero/span and diagnostic checks with a suitable reference while documenting the installed configuration.
Capture the as-left settings, test points, abnormal-state response and revision of 261GSUKBN21. Include photographs of its nameplate and terminal arrangement so the next service event can be traced.

Information to send with a replacement inquiry
Provide the exact model 261GSUKBN21, quantity, serial or revision, application conditions, required connection and approval, and a legible nameplate photograph. Ask for confirmation of accessories and any approved successor.
Keep 261GSUKBN21 in the asset register and maintenance record as the exact search phrase. Record who approved the selected device, what was tested and whether the installed configuration differs from the base family specification.
Final engineering decision
Approve 261GSUKBN21 only when the verified ratings and ordered options match the equipment record. Resolve every discrepancy in code, connection, supply, firmware or process limit before energizing the system.
The published family values for 261GSUKBN21 support identification and initial selection. The device nameplate, matching ABB instructions and the site's approved design determine final suitability.
