Category Specification Fisher Part Number 67CF-1663-38531 Description Positioner and Supply Pressure Gauge Kit Applicable Actuator Fisher 667 and 667AF Series (Size 30 to 120) Pneumatic Actuators Positioner Type Pneumatic Force-Balance, Cylinder Type Input Signal 3 to 15 psig (0.2 to 1.0 bar) standard pneumatic signal. Supply Air Pressure Maximum 150 psig (10.3 bar). Typical operating supply is higher than the signal pressure, often in the 40-100 psig range, to provide sufficient power. Air Consumption Approximately 3.0 SCFM (85 standard liters per minute) at maximum output. Action Direct or Reverse. The action of the positioner (whether the actuator stem extends or retracts with an increasing signal) is field-reversible. Feedback Mechanism Direct mechanical feedback linkage from the actuator's piston rod. Housing Weather-resistant, gasketed aluminum enclosure. Gauge Included pressure gauge for monitoring supply air pressure. Mounting Directly mounts to the actuator as a complete assembly. Performance Linearity: Typically ±1% of span. Hysteresis: Typically less than 0.5% of span. Temperature Limits Standard instrument air quality is required. The positioner is suitable for standard industrial ambient temperatures.
