Setra Systems” Model 260 low differential-pressure transducer offers user-selectable pressure ranges and analog outputs, a standard LCD, and AC/DC excitation on voltage output operation. At a standard accuracy of 1 percent full scale, the unit is the only multi-range transducer to provide fixed-range performance for all selectable ranges. It is a good fit for HVAC control, static room pressure, oven pressurization, furnace draft controls, HVAC service, and retrofit and environmental pollution control. The transducer offers various pressure ranges from 0.1 in. W.C. full scale up through 10 inches W.C. full scale (comparable Pascal ranges available as well). All units may be field-configured as unidirectional or bi-directional ranges, which helps reduce inventory and gives users the flexibility of covering a wide range of typical HVAC applications with a single unit. The transducer”s capacitance-sensor provides better than 0.5 percent full scale long-term stability.
