Setra Systems, Inc. will introduce its new Model 260, “One Size Fits All” low differential pressure transducer at the AHR Expo. The device is said to offer user-selectable pressure ranges and analog outputs, a standard LCD, and a.c./d.c. excitation on voltage output operation. At a standard accuracy of 1 percent FS, the Model 260 is reportedly the only multi-range transducer to provide fixed range performance for all selectable ranges.
According to the company, the transducer is ideal for customers that are unsure of their exact requirements, as the product gives the installer the ability to configure “on the fly.” The Model 260 offers various pressure ranges from 0.1-in w.c. full-scale up through 10-in w.c. full-scale (comparable Pascal ranges available as well). All units may be field-configured as unidirectional or bi-directional ranges, which is said to help reduce inventory and gives users the flexibility of covering a wide range of typical HVAC applications with a single unit.
