Key Parameters & Specifications Parameter / Feature Category Description Product Name Fisher™ 480 Series Pneumatic Valve Positioner Type Force-Balance, Pneumatic (I/P) Primary Function To accurately position a control valve stem in proportion to a pneumatic input signal. Input Signal Standard: 3-15 psi (0.2-1.0 bar) or 6-30 psi (0.4-2.0 bar). Other ranges are available. Output Signal (to Actuator) Supply pressure dependent. Provides the necessary air pressure to the actuator to achieve and hold the required valve position. Supply Pressure Typically up to 100 psig (7 bar) for the 48000 model. Other models may vary. Must be at least 3-5 psi above the input signal and actuator pressure requirements. Action Field-reversible between direct and reverse. • Direct: Input signal increase extends stem (for air-to-open valves). • Reverse: Input signal increase retracts stem (for air-to-close valves). Air Consumption Low, typically around 0.15 SCFM (4 standard liters/min) at steady state. Flow Capacity (Relay) High-capacity relay allows for rapid filling and exhausting of the actuator. Typical exhaust capacity is >1.0 SCFM (28 standard liters/min). Mounting Direct-mounted on the valve yoke, with a mechanical feedback linkage connected to the valve stem. Enclosure Generally, a weatherproof and corrosion-resistant aluminum enclosure. Approvals Suitable for use in hazardous areas due to its purely pneumatic nature. Typical Models 48000 (general purpose), 48001, 48002, etc., with variations for specific actuator types and linkages.

Key Parameters & Specifications Parameter / Feature Category Description Product Name Fisher™ 461 Series Pneumatic Force-Balance Indicator / Transmitter Type Pneumatic Force-Balance Transmitter & Local Indicator Primary Function To provide a local visual indication of a process variable (pressure, level) and/or transmit a proportional pneumatic signal to a control room. Input (Process) Pressure: Various ranges, commonly from 0-30" H₂O (0-7.5 kPa) up to 0-800 psig (0-55 bar). Level: For liquid level applications, using the hydrostatic head pressure. Output Signal Standard Pneumatic Signal: 3-15 psig (0.2-1.0 bar). Supply Pressure Standard: A clean, regulated air supply of 20 psig (1.4 bar) is typical. Must be higher than the output signal (e.g., >18 psig). Accuracy Typically ±0.5% of span for the indicating scale. Scale Large, easy-to-read dial. Can be calibrated in various engineering units (psi, kPa, inches of water, % level, etc.). Operation Two-Wire Pneumatic System: A single supply air line powers the device, and the output signal is superimposed on this supply, varying between 3 and 15 psig. Mounting Direct mounting to a process connection (e.g., a tank nozzle or pipe tap) or to a manifold. Enclosure Rugged, weather-resistant aluminum case with a glass or plastic window. Key Models & Versions • 461: General purpose indicator/transmitter. • 461L: Specifically designed for liquid level measurement. • 461R: Functions as a receiver to display a remote 3-15 psi signal locally.
