MODEL P8/P108 Differential or Absolute Pressure Transducer
The Tavis Model P8 transducer is ideally suited to applications requiring very low
differential pressure measurements. Available in pressure ranges as low as 0.01 psid,
this differential pressure transducer features lowpower consumption and zero and full
scale adjustments. The all welded stainless steel construction and a stable electronics
package combine to produce an extremely accurate, but rugged unit.

*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. |
