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,
Barber-Colman, and older Honeywell devices.
• Three-diaphragm design minimizes calibration 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.
