Overview
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.

For the transmitters 261A, process connections with flush diaphragms are available in a variety of designs and dimensions to meet the requirements of a wide range of sectors,
including industries such as oil and gas, paper, chemicals, food and pharmaceuticals. Special filling fluids are available for applications with high temperatures. For hygienic applications or use in the food industry, select filling fluids that are classified by the US Food and Drug Administration (FDA) as safe for use with food.

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
