Configured for pneumatic pressure control, this all-stainless-steel pressure transducer measures 0 to 7500 psi (0 to 517 bar) gauge pressure with a 100 mV ratiometric output on a cable lead. It holds ±0.25% accuracy with a bonded silicon strain gauge and IP65 rating. It also suits OEM machine pressure sensing.

It holds ±0.25% accuracy with a bonded silicon strain gauge and IP65 rating. It also suits OEM machine pressure sensing.
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.
