Yes, the Oil Quantity is tapped at the oil tank by a Transmitter operated by the EEC. The conformed signal goes to the Cockpit to appear on the lower ECAM. Green is good, and less than 4 quarts causes the alert, a blink of the prompt. The total capacity is 28 quarts, seven gallons.
The Oil Pressure sensing occurs at the FOHE, and the data is likewise supplied to the lower ECAM screen. Normal display is Green, the needle and Digital signals go Red when the Oil Pressure drops below 25 psi. There is an additional condition that involves relative Oil Pressure to N3 set. If this proportional value drops below its minimum but stays above 25psi, a maintenance message is sent.
Oil Temperature is collected at the scavenge return at the oil tank. An alert trips at predetermined low temps, and/or high temps. These alerts I believe cause an alert in the cockpit, an aural one. In addition, when Temps are out of limits, one gets the "Master Caution".
