Here temperatures are usually ISA + 20 Centigrade I am getting up to 195 Fahrenheit degrees readings on the liquid (antifreeze-coolant) The head temperature readings stay within limits Isn´t this too much ? Is it true I might have air trapped in the heads ? Any suggestions ?

Coolant should then flow out of the head. Immediately replace the sender. No more air will be trapped inside the head. Your fill cap is higher than the head, right?
