Fisher 3582 Pneumatic Single Acting Positioner and Type 3582i Electro Pneumatic Valve Positioner
Fisher 3582 pneumatic valve positioners are used with diaphragm-actuated, sliding-stem control valve assemblies. This pneumatic valve positioner receives a pneumatic input signal from a control device and modulates the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal.

The 3582 Series pneumatic valve positioners, shown in figure 1, and the Type 3582i electro-pneumatic valve positioners, shown in figure 2, are used with diaphragm-actuated, sliding-stem control valve assemblies. The pneumatic valve positioners receive a pneumatic input signal from a control device and modulate the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal.

Fisher 3582NS positioners meet typical requirements of the nuclear power industry. The Type 3582NS construction includes materials that provide superior performance at elevated temperature and radiation levels. The O-rings are EPDM (ethylene propylene) and the diaphragms are EPDM/Nomex. EPDM demonstrates superior temperature capability and shelf life over nitrile. The Nomex diaphragm fabric demonstrates improved strength retention at elevated temperature and radiation conditions.

In addition, the Type 3582NS positioner is qualified “commercial grade dedicated” under Fisher’s 10CFR50, Appendix B, quality assurance program.

These can be supplied as 10CFR21 items. Fisher Type 3582i electro-pneumatic valve positioner consists of a Type 582i electro-pneumatic converter installed on a Type 3582 pneumatic valve positioner.

Emerson Fisher brand 3582i positioner provides an accurate valve stem position that is proportional to a dc current input signal.The Type 582i electro-pneumatic converter, shown in figure 5, is a modular unit that can be installed at the factory or in the field(2). The converter receives a dccurrent input signal and provides a proportional pneumatic output signal through a nozzle/flapper arrangement. The pneumatic output signal provides the input signal to the pneumatic positioner, eliminating the need for a remote mounted transducer.

Features


  • For quick analog transmitter replacement, the instrument may be configured with default sensor data, zero level offset, differential process SG, and zero/span procedure only.
  • Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows for use in difficult liquid level, interface, or density applications.
  • An internal temperature sensor enables consistent performance of the digital level controller, despite ambient temperature changes.
  • Mechanical safeguards designed into the digital level controller help to withstand physical abuse often incurred during installation or in transport, without compromising performance.
  • Field wiring connections are in a compartment separated from the electronics. This protects the electronics from any moisture brought into the housing by the field wiring.
  • Includes self-diagnostics that detect an error that may render the process variable measurement inaccurate.
