Digital positioner eases calibration
Flowserve Corp. introduces the Logix 3200IQ and 500si series digital positioners. Both allow quick setup and calibration of either diaphragm- or piston-operated valves without the need for additional handheld devices, software or configuration/calibration tools. The explosion-proof Logix 3200IQ and the intrinsically safe 500si series use piezo technology and inner-loop feedback. The 500si series is available in two models: the 510si and the 520si. The 510si serves the analog (4-20 mA) market, whereas the 520si and the 3200IQ serve the “smart” HART positioner market.
