| Flowserve launches new digital valve positioner Flowserve announces the launch of the Flowserve Logix 3400IQ Foundation Fieldbus digital valve positioner. The 3400IQ features a new FISCO-compliant user interface board, improved potentiometer, piezoelectric technology, and host interoperability to provide operating versatility and fast, easy and accurate calibration. Compatible with any HART or Foundation Fieldbus distributed control system, the Logix 3400IQ controls the position of both single- and double-acting valve actuators with linear or rotary mountings. The Logix 3400IQ is suitable for a wide variety of applications, including oil and gas and chemical processing. The Logix 3400IQ offers fast commissioning, calibration, tuning, and setup in about two minutes from the local user interface. All parameters from the user interface are automatically updated in the Transducer Block, eliminating the need to enter Function Blocks to perform a simple stroke calibration. Local setup and calibration of the 3400IQ does not require a link to a host controller, PC, or hand-held device. With a low 9 VDC supply current and 45 psi air supply for any valve/actuator platform, the 3400IQ makes Foundation Fieldbus installation easy and straightforward. An onboard Quick-Cal button, DIP switches, Jog buttons, and a variable gain selector easily configure the valve and positioner. A blink code list displays valve status updates and confirms calibration at a glance using highly visible LEDs, enabling users to easily determine a valve or actuator is functioning properly so they can quickly diagnose any problems. The standard model of the Logix 3400IQ features instant messaging, as well as hysteresis, dead band, linearity, and repeatability diagnostics. Advanced models are available with actuator pressure sensors that add friction, diagnostic signatures, restriction in air supply, balance pressure, and fitting leakage diagnostics. write your comments about the article :: © 2006 Construction News :: home page |
