  • Accuracy Value 0.25
  • Excitation 10 Vdc
  • Input Resistance 7.5 kΩ
  • Output Resistance 2.5 kΩ
  • Repeatability 0.2% FS
  • Wetted Materials Silicon Diaphragm
  • Zero Balance ±1.5 mV

OMEGA’s PX26 Series pressure sensors feature state-of-the-art silicon technology which permits both sides of the diaphragm to handle liquids. A unique conductive seal between the silicon diaphragm and the plastic housing allows for wet/wet applications and lower production costs than typical gold wire silicon sensors. This new construction has a larger diaphragm than traditional silicon sensors, resulting in increased long-term stability.

Rated 3 out of 5 by from Sometimes OK but sometime not We bought this a month ago for our water pressure loop test, initally it was good and be sensitive to pressure drop changes and read correctly. However, after switching and squeeze air out of in and outlet lines, found the connection was easy to break and get wet so readings were really out of range.

Is any step file (3D) availabe for the PX26-Series ?

Asked by: Anicet
Thank you for your inquiry. We do not have a 3d model for this unit. The dimensional information is listed on the specification page . Hope this was helpful.

What voltage regulator should be used for this transducer? Is there one commercially available?

Asked by: Shishir
Dear Shishir, Excitation: 10 Vdc, 16 Vdc max @ 2 mA Any regulated 10 volts DC power supply will work. You can use our PST-4130 power supply.

Can you recommend a voltage regulator which would be a good fit for this transducer? I looked up the specs but cannot find one which provides output as low as 0.1 V with an input of 10V

Asked by: Shishir
Nominal excitation for the PX26 Series sensor is a regulated 10VDC. With 10VDC applied the output signal from the PX26 would be 0 to 16.7 mVDC for the 1 psi unit, 0 to 50 mVDC for the 5 psi unit and 0 to 100 mVDC for the 15, 30, 100, and 250 psi units. Current draw from the power supply would be 2 mA per unit. We offer a regulated power supply part# FAR-1 that would supply regulated 10VDC.
