Rated for ±0.25% accuracy, this all-stainless-steel pressure transducer measures 0 to 100 psi (0 to 6.89 bar) gauge pressure and provides a 100 mV ratiometric output through a cable lead. 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.
