What's a Jeep Grand Cherokee 318 v8 5.2 liters oil pressure supposed to be at hot idle?

The rule of thumb is 10 psi for every thousand RPM as a minimum spec, but twenty psi seems to be the normal hot oil at idle reading.

I just replaced my original oil pressure sending unit with a standard brand. Went to turn on the car for the past 2 days the light has been on. Checked the oil pressure with a tester read 60 was told I have a faulty part. Anyone have any ideas?

Unsure what the question is. Could be a bad part.
