FAQ

Q1: Is Rosemount 3051TA Absolute Pressure Transmitter More Accurate Than ABB 266GST Pressure Transmitter?

A1: No. Both transmitters have a typical accuracy specification of ±0.04% of span.

Q2: Which Transmitter Has Better Long-term Stability?

A2: The ABB 266GST Pressure Transmitter generally has stronger long term stability standards and could allow for longer calibration intervals.

Q3: Does ABB 266GST Pressure Sensor Support WirelessHART?

A3: No. ABB 266GST Pressure Sensor supports HART, FOUNDATION Fieldbus and PROFIBUS PA but not WirelessHART connection.

Q4: Which Transmitter Is Better For Oil And Gas Applications?

A4: Both are ideally suited to oil and gas applications. However, Rosemount 3051TA Pressure Sensor In-Line Pressure Transmitter is generally selected because of its extensive industrial use and global support network.

Q5: Is ABB 266GST Transmitter A Suitable Replacement For Rosemount 3051TA Transmitter?

A5: Yes. ABB 266GST Transmitter is a very good contender, especially for plants already standardised on ABB systems.
