Default Oil Pressure on cold start up??

I've noticed that when first started oil pressure reads anywhere from 60 to 80 psi, after warming up it reads 40-50 psi. car only has 24,000 miles, oil changed often, is this the oil sending unit going bad? sending false signals? Thanks!

Cold oil requires more pressure to move it. Since it thins with heat it will be higher at start up and gradually drop to the lower range. It is normal.
