261AC, 261AG, 261AJ, 261AM, 261AN – ABB Absolute pressure transmitter

The compact transmitter class for absolute pressure with frontbonded diaphragms works within a broad selection of variants, options, fill fluids and wetted materials.


The compact, robust transmitter housing is made of 316 stainless steel as a standard. Due to its high corrosion resistance it can be used in a wide variety of process and ambient conditions without any problems.
The user friendly display allows simple and intuitive local transmitter operation. Full device support, including diagnostic / maintenance information is guaranteed via the Device Type Manager software used in either a stand alone or system engineering tool. The transmitter provides local zero and span adjustments even without display.The wide range of available process connections meets even special industrial requirements:

  • Threaded connections: e.g. for the power, pulp/paper, or oil and gas industries
  • Flange connections: e.g. for the chemical industry
  • Hygienic connections: e.g. for the pharmaceutical or food and beverages industries


  • Base accuracy: ± 0.1 %
  • Span limits: 6 to 3000 kPa abs; 45 mmHg to 435 psia
  • Output signal: 4 to 20 mA, HART
  • Conforms to SIL2 acc. to IEC 61508 / IEC 61511
  • Full compliance with PED Category III
