These would be used in an agricultural/harvesting, dirty air environment. What can be done to keep the lines clean from debris?

Asked by: DanR
The only thing we can suggest is an inline filtering system of some sort

What is the power consumption of these sensors

Asked by: Eli T
Thank you for your inquiry. We believe the best assistance would come from speaking to us directly at 888-826-6342 ask for the Pressure/Strain Department Mon. &ndash; Fri. (HOURS 8:30AM - 5:30PM EST) or e-mail us at pressure@dwyeromega.com .

What is the calibration factor (psi/V) according to the factory calibration? This information was not provided in the User Manual.

Asked by: Ashslay
Thank you for your inquiry, the output is 5 Vdc &plusmn;50 mV over the full range of the sensor

Could you please tell me the resolution of the A/D converter on model PX2650-10D5V?

Asked by: WesF
The PX2650-10D5V simply has a linear 0 to 5VDC signal output over it's 0 to 10&quot; wc differential pressure. Signal resolution wonder depend on the input signal resolution of the device you are reading this signal with.
