Product Announcement from OMEGA Engineering, Inc.
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 PXM309 Series 70 mbar to 700 bar Gage Pressure 350 mbar to 20 bar Absolute Pressure 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 or IP67 environmental rating (depending upon style and termination).
