Measuring 0 to 30 psi (0 to 2.07 bar) gauge pressure, this all-stainless-steel pressure transducer outputs 0 to 5 V DC through a cable lead at ±0.25% accuracy. An oil-filled silicon sensor gives low drift in an IP65 housing. It suits hydraulic system pressure monitoring and compressor and pump monitoring.
Measuring 0 to 30 psi (0 to 2.07 bar) gauge pressure, this all-stainless-steel pressure transducer outputs 0 to 5 V DC through a cable lead at ±0.25% accuracy. An oil-filled silicon sensor gives low drift in an IP65 housing. It suits 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.
