OMEGA's pressure transducer PXM309 series industrial combine two of our precision manufacturing techniques. Low pressure ranges from 0-70 mbar up to 0-3.5 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 Gauge pressure ranges, from 0-7 bar up to 0-700 bar, use precision semiconductor strain gauges that are fused directly to the stainless steel diaphragm yielding a rugged, durable bond that assures long life and high stability.

The PXM309 series transducers are available in absolute, or gauge (relative) pressure and are sealed to an IP65 or IP67 environmental rating, depending on the model.(See table below).
