ABB Absolute Pressure Transmitter 261AS
Part of the compact transmitter class for absolute pressure within the 2600T series, the Absolute Pressure Transmitter 261AS has a dependable sensing system featuring highly innovative digital technologies. With a base accuracy of ± 0.1 %, this device transmits a 4 to 20 mA, HART® output signal and offers a substantial turndown ratio of up to 20:1.
316 stainless steel housing is standard for the strong, streamlined 261AS, providing for issue-free performance in an extensive range of process and ambient conditions, due to its elevated corrosion resistance. This instrument’s intuitive display allows for easy local transmitter operation. Complete device support, including diagnostic and maintenance information, is ensured via the Device Type Manager software used in either an individual or system engineering tool.
Capable of delivering local zero and span adjustments, even without display, the 261AS offers the following span limits: 0.3 to 3000 kPa abs; 2.25 mmHg to 435 psia. This transmitter fully complies with PED Category III and follows SIL2 acc. to IEC 61508 / IEC 61511.
