Pneumatic Pressure Controllers
PP905 Static Pressure Sensor
One-pipe, direct-or reverse-acting pressure sensor used with RP908/RP920 Controllers to provide control of duct static, velocity, or differential pressure in airflow applications. Replacement devices available for Johnson, Powers, Robertshaw, BarberColman, and older Honeywell devices.
• Three-diaphragm design minimizes cal bration shift with static pressure changes in velocity pressure applications.
• Not sensitive to normal supply air variations.
• Continuous static, total, velocity, or differential pressure indication available by using differential pressure gage.
