Supplier Fisher 2500 Pneumatic Level Controller Jakarta

WWW.DISTRIBUTORALATINDUSTRI.COM | The Fisher 2500 Pneumatic Level Controller is a pneumatic level controller designed to regulate liquid level, liquid-liquid interface level, and density (specific gravity) in a wide range of industrial applications. It is well known for its simple, rugged, and reliable construction, making it widely used in oil and gas, petrochemical, power generation, and other process industries. The Fisher 2500 is commonly paired with the Fisher 249 Series displacer sensor to provide accurate and stable level measurement and control.

The Fisher 2500 operates based on the principle of buoyancy changes acting on a displacer. Variations in liquid level cause movement of the torque tube within the sensor assembly, which is then converted into a pneumatic output signal to operate a control valve or other final control elements. This system enables proportional level control with fast and stable response to process changes.

The controller features a mechanical design with very few moving parts, minimizing friction and enhancing long-term operational reliability. Set point, proportional band, and control action can be easily adjusted using external knobs without requiring additional components. Furthermore, the control action is field-reversible, allowing it to be configured as either direct acting or reverse acting to suit specific application requirements.

The Fisher 2500 uses clean, dry instrument air or natural gas as the supply medium and provides a standard pneumatic output signal of 3–15 psig (0.2–1.0 bar) or 6–30 psig (0.4–2.0 bar) for controlling final control elements. Its pneumatic relay system is designed for efficient air consumption, with the exhaust operating only when the input signal changes.
