W.C. to .25 - 2.5 kPa FS Bidirectional Ranges: ±0.1 - 10 in. W.C. to ±.25 - 2.5 kPa FS Air or Non-Conducting Gas Visit Setra Online: http://www.setra.com ments. The units are temperature compsensated to within ±0.03%FS/oF (0.054%FS/oC) for zero and span. The Model 260 utilizes an all stainless steel micro-tig welded sensor. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close to the diaphragm, form a variable capacitor. Positive pressure moves the diaphragm toward the electrode, increasing the capacitance. A decrease in pressure moves the diaphragm away from the electrode, decreasing the capacitance. The change in capacitance is detected and converted to a linear DC electrical signal by Setra’s custom ASIC technology.

The 260 Series is offered with fi eld selectable high level analog outputs of 0 to 5, and 0 to 10 VDC, or 4 to 20 mA. Used in Building Energy Management Systems, these transducers are capable of measuring pressures and flows with the performance necessary for proper building pressurization and air fl ow control. The 260 Series transducers can be confi gured for air pressure ranges as low as 0.1 in. W.C. full scale, with pascal ranges as low as 25 Pa full scale.
