hi..... this is Prof.Dr.wael kamel from EGreck compony . i want oxygen sensor used to measure percentage of oxygen in the ullage "space containts of air and hydrocarbon vapor "in the hydrocarbon tank at normal temperature (0-50)C , working absolute pressure (0-50)psi ,sensor is "hydrocarbon resistance" motion insensitive of the hydrocarbon vapor .i want to know , can i have data sheet gives (oxygen percentage related to the output voltage ) comes from sensor using this output voltage to control solenoid valve.please confirm if you find that one , give me also the pricethanks a lot
