Flowserve Corp., a provider of fluid motion and control products and services, introduces the Logix 3200IQ and 500si series high-performance digital positioners. Offering quick setup and calibration of either diaphragm- or piston-operated valves without the need for additional handheld devices, software or configuration/calibration tools, the Logix 3200IQ and 500si series are used in various industries employing control valves. The explosion-proof Logix 3200IQ and the intrinsically safe 500si series use state-of-the-art piezo technology and inner-loop feedback to provide superior performance, control, and reliability with minimal air consumption in compact, lightweight and modular designs. The 500si series is available in two models - the 510si and the 520si. While the 510si serves the analog (4-20 mA) market, the 520si, like its sister, the 3200IQ, serves the "smart" HART® positioner market. By using the HART communication protocol, the Logix 520si and 3200IQ can provide wide-ranging data to a facility's control system (DCS or PLC) or to its maintenance database software.
