New product: One size fits all pressure transducer
Pressure transducer fits any application.
Setra Systems ' Model 260 capacitance-sensor is a 'One size fits all' low differential pressure transducer, the company says. The unit 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% FS, the company claims it is the only multi-range transducer to provide fixed range performance for all selectable ranges.
The Model 260 offers various pressure ranges from 0.1 inH2O full-scale up through 10-inH2O 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 sensor boasts better than 0.5% FS long-term stability and the company guarantees uniform range-to-range accuracy. User does not have to be concerned with jumpers, or dip switches as there are separate slide switches for the range selection, analog output, and unidirectional or bi-directional ranging of the span. Additional benefits include immediate feedback of range and output status after re-configuring.
