improve accuracy of barometer
We use a mercury barometer with an error of 0.2 mbar as reference. Can we align a T2514 with our reference and most important - will it be long term stable?
regards

Re: improve accuracy of barometer
Yes, you can :-)
Typical long term stability parameter defined by pressure sensing element manufacturer there is -1mbar/yr. Device accuracy is defined into users manual. It depends on you how often you would like to do aligntment. For device adjustment use Tsensor software

Re: improve accuracy of barometer
Thank you Petr
Yes - I understand - could be aligned - but makes no sense with the long term stability.
So we have to stay with our expensive solution.
