ABB typically configures 266 pressure transmitters according
to the user requirements. A typical configuration includes:
• TAG number
• Calibrated span
• Output linearization
• LCD display configuration
Hazardous area considerations
The transmitter must be installed in hazardous area only if it is
properly certified. The certification plate is permanently fixed
on the neck of the transmitter top housing. The 266 Pressure
Transmitter Line can have the following certifications:
