Rated for ±0.25% accuracy, this all-stainless-steel pressure transducer measures 0 to 7500 psi (0 to 517 bar) gauge pressure and provides a 4 to 20 mA output through a mini DIN connector. Its bonded silicon strain gauge keeps drift low. It is used for hydraulic system pressure monitoring and compressor and pump monitoring.

Omega's PX309 Series models below 100 psi use a high-accuracy silicon sensor protected by an oil-filled stainless steel diaphragm.
Units 100 psi and above use silicon strain gauges molecularly bonded to the stainless steel diaphragm.
