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 
PXM309: 2 m (6.6')  
cable IP67 rating
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.
