DPTMR/OUT 1-10WC LC STAT
Setra Systems 260 pressure transducers sense differential or gauge (static) pressure and convert this pressure difference to a proportional electrical output for either field selectable unidirectional or bidirectional pressure ranges. The 260 Series is offered with field selectable high level analog outputs of 1 to 5, 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 flow control. The 260 Series transducers can be configured for air pressure ranges as low as 0.1 in. W.C. full scale. Static standard accuracy is ±1.0% full scale in normal ambient temperature environments. The units are temperature compsensated to within ±0.02%FS/o F (0.036%FS/o C) 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
