FAIRCHILD - Relays
Model 85D Multi-Stage Biasing Relay is a precision control combining the sensitivity of a precision pressure regulator with positive biasing capability. This compact, pilot-operated device offers unusually high output capacity with minimal air consumption, while providing excellent protection against supply or output pressure variations.
Features
• The versatile Model 85D is recommended for use in systems requiring precision pressure maintenance and instrument biasing, in dead end service and instrument panel supply applications
• The basic mathematical expression for the Fairchild Model 85D is PO = PS + K where PO is output pressure, PS is signal pressure and K is the spring constant
• Two stage pilot operation allows precise control of set points
• 14 SCFM flow capacity in a small size unit allows use in applications requiring high flow and/or fast response
• Low air consumption preserves air and other costly gases
• Compact size permits installation where space is limited
• Available in 1/8", 1/4" and 3/8" standard port sizes - versatility makes it easy to design into new and existing applications
• The basic mathematical expression for the Fairchild Model 85D is PO = PS + K where PO is output pressure, PS is signal pressure and K is the spring constant
• Two stage pilot operation allows precise control of set points
• 14 SCFM flow capacity in a small size unit allows use in applications requiring high flow and/or fast response
• Low air consumption preserves air and other costly gases
• Compact size permits installation where space is limited
• Available in 1/8", 1/4" and 3/8" standard port sizes - versatility makes it easy to design into new and existing applications
