OMEGA’s PXM309 Series industrial
pressure transducers utilize two
of our precision manufacturing
techniques. Low pressure ranges
from 70 mb to 3.5 bar, and absolute
ranges to 20 bar use a precision
micromachined silicon sensor
protected by a stainless steel
diaphragm. A thin film of oil transfers

the pressure and assures the high
accuracy and stability of the sensor.
Medium and high gage pressure
ranges, from 7 bar up to 700 bar,
use precision semiconductor strain
gages that are fused directly to the
stainless steel diaphragm yielding a
rugged, durable bond that assures
long life and high stability. These

precision techniques produce
an accuracy of 0.25% FS BSL
@25ºC and a total error band of
1% on most ranges. The PXM309
Series transducers are available
in absolute, or gage (relative)
pressure and are sealed to an IP65
environmental rating.
