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.

difference to a proportional electrical output
for either fi eld selectable unidirectional
or bidirectional pressure ranges. 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.
