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.

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.

Pressure measurements inside small ID thin tubing
We use these pressure gauges in combination with the PLATINUM™ Series Digital Panel Meters (DP8PT-006) to determine the pressure inside thin flexible tubing as water is flowing inside. WE use three of these pressure gauges along the tubing and can determine the pressure changes with the experimental conditions. They work well and are responsive.

This order and every one I have placed with Omega has been handled very efficiently.

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

The PX26-001DV shows an output of 10mv/V, according to your selector menu on this web page, but all data sheets indicate 1 psi models as having 0-16.7 mV output when connected to a 10V DC power supply. Which is it?
The error is in the part number builder in the product page. The 1 PSI range units in both the Differential and Gage models have a 1.67 mV/V sensitivity. Having the error corrected

We are using the +- 1 psi differential pressure sensor. When we connect the pressure sensors as shown in the data sheet (with 10V input), we are measuring the ouput voltage to 2.6V. Do you know why, is it an off-set voltage?
Are you wiring the sensor differentially (power connections separate from signal connections). If the negative signal connection and the negative excitation are connected to a common point you will get a high voltage signal output. If the connects are not commoned together you most likely have damaged sensor sensor

I'm using a PX26-005DV to measure the pressure drop . At high flow rates, the sensor works but at low flow rates where pressure drop is 0.01 psi, the sensor gives negative value. Is it because of range of the sensor? would PX26-001DV solve the problem?
Hoomichi, you are trying to measure a pressure drop that is too low to be captured by this sensor. This is a low cost unit that can measure at quarter percent accuracy. Please see the PX409 differential series models for better measurement. For more questions please email pressure@omega.com

Do you have recommended NI DAQ to log pressure measured by PX26?
We would not have any information on what NI DAQ would work with the PX26 transducer.

We are using an omega sensor that looks to be from the PX26 family for differential pressure. The sensor is etched with the code 6BF60 and 201033N. We want to have a spare. Can anyone equate the sensor we have with a current model we can purchase?
Code 6BF6D is the equivalent to our PX26-005DV

This sensor says that it is for wet applications.... Is it possible to use this with air, or would that not work well/correctly?
Any of our sensors that we state are for wet application will also work fine use with gases. Air would be just fine.

How high of a vacuum will this sensor tolerate? I don't need a vacuum readout, but it would likely experience a vacuum equivalent of ~50-75 psi.
This unit is not designed for vacuum application, if this application requires a vacuum measurement you may want to choose a different product.
