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. Features: - 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.

Low cost was the primary driving force for both manufacturers and users. But while they were popular with designers and owners, many maintenance managers considered them nightmares: difficult to service, prone to breakdowns, inadequately protected from the elements. Today, everything has changed. Gone is the concept of one size fits all. Buyers have more options, including practically all of the same features found in other types of building HVAC systems, from economizers for energy conservation and prewired interfaces for building automation systems to heat w noblex Tue, 24 Jan 2012 13:47:30 GMT
