Electro Pneumatic Rotary Positioner

Electro Pneumatic Rotary Positioner

OVERVIEW

An Electro-Pneumatic Rotary Positioner is a device used to control the position of rotary actuators and valves in process automation systems. It receives an electrical signal from a control system and converts it into a proportional pneumatic output, which adjusts the position of the actuator or valve. This ensures precise control over various process parameters such as flow, pressure, and temperature.

SPECIFICATION

  • Input Signal: 4-20 mA or 0-10 V DC
  • Output Pressure Range: 3-15 psi (0.2-1.0 bar) or customizable ranges
  • Supply Pressure: 20-100 psi (1.4-7 bar), depending on the model
  • Rotation Angle: Up to 90° or more, depending on the actuator
  • Accuracy: Typically within ±0.5% of full scale
  • Ambient Temperature: -40°C to +85°C (-40°F to +185°F)
  • Housing: Explosion-proof or weather-proof enclosures available (IP65, IP66, NEMA 4X)
  • Certification: ATEX, IECEx, FM, CSA for hazardous area applications

FEATURES

  • High Precision: Ensures accurate positioning of rotary actuators and valves for optimal control of process variables.
  • Fast Response Time: Rapid adjustment to changes in control signals for dynamic process environments.
  • Durability: Robust construction to withstand harsh industrial environments, including extreme temperatures, dust, and moisture.
  • Feedback Capability: Provides position feedback to the control system for closed-loop control.
  • Fail-Safe Operation: Options available for fail-safe positions in case of signal loss or power failure.
  • Easy Calibration: Simple calibration procedures for quick setup and maintenance.
  • Compatibility: Suitable for use with a wide range of rotary actuators and valves.
