Absolute pressure transmitter 261 series

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
