*Static Error Band is defined as the maximum allowed deviation from a best fit straight line which minimizes errors due to the combined effects of nonlinearity, hysteresis, resolution, and non-repeatability.
*Temperature Error is defined
as the maximum allowed
deviation from a best fit straight
line which minimizes errors due
to temperature over the range of
65 F to + 165 F.
*Frequency Response given
is for electronics only. Actual
frequency response will depend
on pressure range and media.
(1)
All Tavis transducers can be supplied for corrosive media applications. Materials used for this purpose are 17-4PH SS,
17-7PH SS and Iconel . Specify model P104 for this feature.
(2)
Closer tolerances and higher temperature operation may be supplied. Consult factory for special requirements.
(3)
Add 0.5 inches to length for absolute units with ranges less than 5 psia.
