ATEX EEX approval lets the positioner be used in the European market. And Fieldbus support means the positioner can communicate via a fourth protocol, in addition to 4 to 20-mA analog, HART, and PROFIBUS. The device features a microprocessor, autocalibration, digital control of valve flow characteristics, password protection, process diagnostics, alarm settings, and multilanguage menus. The D3's combination of computeroptimized pneumatic relay and piezoelectric valves provides low steady-state air consumption measuring 0.01 scfm, for a near-zero bleed rate. Splitspindle design and a friction coupling for the feedback potentiometer lets the D3 mount on almost any actuator and in any position.
